1
00:00:01,334 --> 00:00:04,174
CHARLIE: Hey guys
Charlie here today we're
hanging out in Colorado
2
00:00:04,237 --> 00:00:05,667
somewhere near Boulder!
3
00:00:05,739 --> 00:00:07,669
And we're here hanging out with
our friends from the Center
4
00:00:07,741 --> 00:00:09,841
for Severe Weather Research.
5
00:00:09,909 --> 00:00:11,179
I think they're
here right now. Oh man.
6
00:00:11,244 --> 00:00:12,414
KIRBY: Come on Charles!
7
00:00:12,479 --> 00:00:13,609
CHARLIE: We gotta go guys!
KIRBY: Hop in!
8
00:00:13,680 --> 00:00:15,020
CHARLIE: Nothing like hanging
out with some storm chasers
9
00:00:15,081 --> 00:00:16,121
to start your day!
10
00:00:16,182 --> 00:00:17,452
KIRBY: We're hoping
for a giant storm!
11
00:00:17,517 --> 00:00:19,217
Let's go chase it down.
12
00:00:40,940 --> 00:00:43,210
CHARLIE: I don't know Kirb,
Moonbows are pretty cool.
13
00:00:43,276 --> 00:00:45,206
KIRBY: Trust me, this
will gonna be bumpin'.
14
00:00:45,278 --> 00:00:46,908
CHARLIE: What's up guys!
KIRBY: Hey!
15
00:00:46,980 --> 00:00:48,380
CHARLIE: I'm Charlie.
KIRBY: I'm Kirby.
16
00:00:48,448 --> 00:00:50,578
CHARLIE: We're so
excited that you're here,
alright, check it out.
17
00:00:50,650 --> 00:00:52,820
The most frustrating
thing just happened.
18
00:00:52,886 --> 00:00:53,986
KIRBY: The worst.
19
00:00:54,054 --> 00:00:56,124
CHARLIE: Just like ten minutes
ago we were outside in front
20
00:00:56,189 --> 00:00:57,659
getting ready to
go to the beach.
21
00:00:57,724 --> 00:00:59,164
We had everything we needed.
22
00:00:59,225 --> 00:01:00,585
We were ready to go.
23
00:01:00,660 --> 00:01:02,600
KIRBY: Umbrella?
CHARLIE: Check. Sunscreen?
24
00:01:02,662 --> 00:01:04,132
KIRBY: Check. Goggles?
25
00:01:04,197 --> 00:01:05,927
CHARLIE: Check!
Ready to roll.
26
00:01:05,999 --> 00:01:07,899
KIRBY: It's raining!
27
00:01:07,967 --> 00:01:09,597
CHARLIE: No!
28
00:01:09,669 --> 00:01:10,999
(sirens)
29
00:01:11,071 --> 00:01:12,341
KIRBY: Is that a
tornado warning?
30
00:01:12,405 --> 00:01:13,735
CHARLIE: No!
31
00:01:13,807 --> 00:01:16,677
KIRBY: We gotta get
inside quick until this
thing passes, come on.
32
00:01:16,743 --> 00:01:18,283
CHARLIE: It's
storming outside!
33
00:01:18,344 --> 00:01:19,484
KIRBY: And nado-ing!
34
00:01:19,546 --> 00:01:20,606
CHARLIE: Tornado sirens!
35
00:01:20,680 --> 00:01:21,980
KIRBY: I just wanna
go to the beach.
36
00:01:22,048 --> 00:01:23,248
CHARLIE: That's
definitely not happening.
37
00:01:23,316 --> 00:01:24,276
KIRBY: I know.
38
00:01:24,350 --> 00:01:25,790
CHARLIE: So, we just got
robbed of a beach day.
39
00:01:25,852 --> 00:01:27,652
And we wanna make sure that,
that never happens again!
40
00:01:27,720 --> 00:01:28,760
KIRBY: Never.
41
00:01:28,822 --> 00:01:30,592
CHARLIE: So today, we're
checking out weather but
42
00:01:30,657 --> 00:01:33,027
not just any weather,
the extreme weather.
43
00:01:33,093 --> 00:01:34,163
KIRBY: The big weather.
44
00:01:34,227 --> 00:01:37,157
CHARLIE: The beach day
breaking, plan canceling,
no outside playing,
45
00:01:37,230 --> 00:01:39,000
big bad, nasty weather!
46
00:01:39,065 --> 00:01:41,935
Today, we're unraveling
the world of...
47
00:01:43,903 --> 00:01:46,343
KIRBY: Tornadoes
and Hurricanes!
48
00:01:46,406 --> 00:01:50,106
CHARLIE: Okay, so for the
past couple minutes Kirby
and I have put some effort
49
00:01:50,176 --> 00:01:52,076
into checking out some
weather stuff.
50
00:01:52,145 --> 00:01:53,505
KIRBY: The neatest
weather stuff.
51
00:01:53,580 --> 00:01:55,750
CHARLIE: And
there's some pretty neat
weather stuff out there.
52
00:01:55,815 --> 00:01:57,345
Like moonbows.
53
00:01:57,417 --> 00:02:01,017
Rainbows that show up at night
when the moon's almost full.
54
00:02:02,622 --> 00:02:04,062
And thundersnow.
55
00:02:04,124 --> 00:02:07,164
That's a blizzard with tons
of thunder and lightning.
56
00:02:09,295 --> 00:02:15,895
There are crazy hail storms,
sand storms,
57
00:02:15,969 --> 00:02:21,169
and mammatus clouds that
look like colorful fluffy
egg cartons in the sky.
58
00:02:21,975 --> 00:02:23,835
But what gets us
really excited...
59
00:02:23,910 --> 00:02:25,780
KIRBY: Tornadoes
and hurricanes.
60
00:02:25,845 --> 00:02:30,175
CHARLIE: Crazy strong storm
events that are basically
the closest thing we have to
61
00:02:30,250 --> 00:02:33,890
mother nature sucker punching
earth right in the jaw.
62
00:02:35,922 --> 00:02:39,862
KIRBY: Hurricanes and
tornadoes are incredibly
powerful storm events.
63
00:02:39,926 --> 00:02:44,426
They're like someone took
a normal storm, cranked
the wind speed up to 11,
64
00:02:44,497 --> 00:02:49,667
and forced the whole
thing into a giant
torpedo of destruction.
65
00:02:49,736 --> 00:02:53,666
But for real, these things are
really nothing to mess around
66
00:02:53,740 --> 00:02:56,110
with because they can
be super dangerous.
67
00:02:56,176 --> 00:03:00,076
So, safety is the number
one thing when you're in an
area that is experiencing
68
00:03:00,146 --> 00:03:02,716
a hurricane or a tornado.
69
00:03:02,782 --> 00:03:05,892
CHARLIE: So, instead
of freaking out about the fact
that there's a tornado warning
70
00:03:05,952 --> 00:03:10,362
going on outside, Kirby
and I decided to cope by
doing what we do best.
71
00:03:10,423 --> 00:03:12,163
KIRBY: A little
research and crafting.
72
00:03:12,225 --> 00:03:14,355
CHARLIE: First up, tornadoes.
73
00:03:14,427 --> 00:03:17,497
Tornadoes don't just
happen during any storm.
74
00:03:17,564 --> 00:03:20,834
They happen during
supercell thunderstorms.
75
00:03:20,900 --> 00:03:25,940
Cool science word, Supercell
Thunderstorms, they're really
intense thunderstorms that
76
00:03:26,005 --> 00:03:30,005
have swirling columns
of air in the middle that
kind of look like this...
77
00:03:30,076 --> 00:03:34,776
That swirling wind area
is called the mesocyclone.
78
00:03:34,847 --> 00:03:38,987
When there's really low air
pressure, the mesocyclone
starts making its way to the
79
00:03:39,052 --> 00:03:41,752
ground, mixing with
cold and hot air.
80
00:03:41,821 --> 00:03:44,221
When the swirling wind
mass touches the ground.
81
00:03:44,290 --> 00:03:47,630
That's when we've got
a tornado on our hands.
82
00:03:47,694 --> 00:03:51,634
KIRBY: And that's also
when we have a tornado
warning on our hands.
83
00:03:51,698 --> 00:03:53,468
CHARLIE: This is how it works.
84
00:03:53,533 --> 00:03:55,173
First there's a siren.
85
00:03:55,235 --> 00:03:56,995
(siren)
86
00:03:57,070 --> 00:04:00,170
Then, on TV something
like this usually shows up.
87
00:04:00,240 --> 00:04:04,240
If there's a tornado watch,
that means the weather people
think there's a chance that
88
00:04:04,310 --> 00:04:07,910
mesocyclone might be
touching down sometime soon.
89
00:04:07,981 --> 00:04:12,191
If there's a tornado
warning, that means the
mesocyclone has touched down,
90
00:04:12,252 --> 00:04:15,492
there's a tornado somewhere
and there could be more.
91
00:04:15,555 --> 00:04:21,025
So, a tornado watch is like
a big maybe, but a tornado
warning is like a heads-up
92
00:04:21,094 --> 00:04:24,964
man, a tornado's been
spotted so get to your
basement and be safe!
93
00:04:25,031 --> 00:04:26,471
Cool cool?
Cool cool.
94
00:04:26,532 --> 00:04:28,372
KIRBY: Guys, guys,
this is great!
95
00:04:28,434 --> 00:04:30,374
But can we please talk about
the fact that there are
96
00:04:30,436 --> 00:04:32,606
a bunch of different
kinds of tornadoes?
97
00:04:32,672 --> 00:04:33,872
So weird!
98
00:04:33,940 --> 00:04:35,210
Check it out!
99
00:04:35,275 --> 00:04:37,305
So first you have
your standard tornado.
100
00:04:37,377 --> 00:04:41,147
Basic shape, swirling wind,
single cone, etcetera.
101
00:04:41,214 --> 00:04:43,224
Then you have your land spout.
102
00:04:43,283 --> 00:04:46,023
Kind of like a junior tornado
that forms from the ground up.
103
00:04:46,085 --> 00:04:49,815
Waterspout tornadoes form
over bodies of water.
104
00:04:49,889 --> 00:04:54,059
Multiple vortex tornadoes have
more than one touchdown point.
105
00:04:54,127 --> 00:04:58,557
And my personal favorite,
a family of tornadoes.
106
00:04:58,631 --> 00:05:04,141
Like a herd of tornadoes
thundering across an area, all
coming from the same cloud.
107
00:05:04,203 --> 00:05:05,713
CHARLIE: So those
are tornadoes.
108
00:05:05,772 --> 00:05:06,742
KIRBY: Tornadoes.
109
00:05:06,806 --> 00:05:08,136
CHARLIE: Tornadoes,
we got 'em down.
110
00:05:08,207 --> 00:05:09,537
Hurricane time?
111
00:05:09,609 --> 00:05:11,439
KIRBY: Hurricane time.
CHARLIE: Let's dive in.
112
00:05:11,944 --> 00:05:15,384
Hurricanes always
start as storms in the
middle of the ocean.
113
00:05:15,448 --> 00:05:19,948
When the temperature gets
warm enough, winds start
pushing the air up and out.
114
00:05:20,019 --> 00:05:24,289
The air keeps rising because
it's so warm and humid,
forming this enormous donut
115
00:05:24,357 --> 00:05:28,027
shaped storm, that slowly
makes its way toward land.
116
00:05:28,094 --> 00:05:31,604
Here's the thing about
hurricanes, they're massively
bigger than tornadoes
117
00:05:31,664 --> 00:05:34,204
like 1,000 times bigger.
118
00:05:34,267 --> 00:05:39,107
One hurricane can cover
the entire east coast for the
United States while tornadoes
119
00:05:39,172 --> 00:05:42,542
usually move through
just one town at a time.
120
00:05:42,608 --> 00:05:46,308
If the wind of one of
these storms reaches
38 miles per hour,
121
00:05:46,379 --> 00:05:49,649
weather people call it
a tropical depression.
122
00:05:49,716 --> 00:05:55,016
If those winds boost up to
39 miles per hour, it's
now a tropical storm and
123
00:05:55,088 --> 00:06:00,488
we give it a name like
Jeremy, or Jillian, or
Julian, or anything else.
124
00:06:01,127 --> 00:06:06,897
Once Julian hits 74 miles
per hour, now he's graduated
to hurricane status.
125
00:06:06,966 --> 00:06:08,196
Congrats Julian.
126
00:06:08,267 --> 00:06:11,137
We're so proud of you.
You big old hurricane.
127
00:06:11,204 --> 00:06:12,944
KIRBY: So, we got
the basics down.
128
00:06:13,005 --> 00:06:15,805
CHARLIE: Yeah, but
we want to know how to
predict these bad boys.
129
00:06:15,875 --> 00:06:20,005
Like we know that tornadoes
come from supercell
thunderstorms and hurricanes
130
00:06:20,079 --> 00:06:22,749
come from warm, humid
air over the ocean.
131
00:06:22,815 --> 00:06:24,515
But that's not really enough.
132
00:06:24,584 --> 00:06:28,254
To really understand these
things, we need to become...
133
00:06:28,321 --> 00:06:29,791
Weather men!
134
00:06:29,856 --> 00:06:31,056
KIRBY: And weather women!
135
00:06:31,124 --> 00:06:32,394
CHARLIE: Weather people!
136
00:06:32,458 --> 00:06:34,928
Stick around for a news
weather update from E.W.N.!
137
00:06:34,994 --> 00:06:36,664
KIRBY: The Extreme
Weather Network.
138
00:06:36,729 --> 00:06:40,029
CHARLIE: 80% chance of
fun weather facts heading
your way so stick around.
139
00:06:40,099 --> 00:06:41,529
KIRBY: That was really bad.
140
00:06:41,601 --> 00:06:43,301
CHARLIE: Not my best line.
141
00:06:44,670 --> 00:06:48,040
KIRBY: Weird but true,
waterspouts can lift sea
creatures out of the water
142
00:06:48,107 --> 00:06:50,877
causing them to rain
down from the sky!
143
00:06:54,614 --> 00:06:56,884
CHARLIE: Today we're
checking out extreme weather.
144
00:06:56,949 --> 00:06:58,279
KIRBY: Tornadoes
and Hurricanes.
145
00:06:58,351 --> 00:06:59,851
CHARLIE: Tornadoes
and hurricanes.
146
00:06:59,919 --> 00:07:03,159
We kind of squared away
what they are, we wanna
learn how to predict them.
147
00:07:03,222 --> 00:07:04,792
We need to become.
148
00:07:04,857 --> 00:07:06,787
KIRBY: Weather people!
CHARLIE: Weather people!
149
00:07:06,859 --> 00:07:09,859
But we found out that
if weather's your thing, there
are a whole bunch of different
150
00:07:09,929 --> 00:07:11,399
jobs you can do to study it.
151
00:07:11,464 --> 00:07:13,834
More than just your television
weatherman slash lady.
152
00:07:13,900 --> 00:07:15,070
Wanna check em out?
153
00:07:15,134 --> 00:07:16,444
KIRBY: I'm game.
CHARLIE: Awesome!
154
00:07:16,502 --> 00:07:19,312
First, we'll start out
with your television
man slash woman.
155
00:07:19,372 --> 00:07:24,642
The people you see on
the TV, on the news, are
usually meteorologists.
156
00:07:24,710 --> 00:07:28,580
They study short term
weather, like day to day
weather that might last
157
00:07:28,648 --> 00:07:31,218
from a few days to a few weeks.
158
00:07:31,284 --> 00:07:35,964
They use complex computer
models to predict patterns,
and give us the weather for
159
00:07:36,022 --> 00:07:37,722
the week or the night.
160
00:07:37,790 --> 00:07:40,490
Usually presenting it in
front of a green screen.
161
00:07:40,560 --> 00:07:43,700
KIRBY: I'm meteorologist
Kirby with the
Extreme Weather Network.
162
00:07:43,763 --> 00:07:46,773
CHARLIE: So that's a
meteorologist, but I know
that being in front of
163
00:07:46,833 --> 00:07:48,873
the camera is not for everyone.
164
00:07:48,935 --> 00:07:52,405
So, for those really smart
science people who get jacked
up about global weather,
165
00:07:52,472 --> 00:07:54,772
maybe climatology
is your thing.
166
00:07:54,841 --> 00:07:58,011
You might wanna
become a climatologist
like Greg over here.
167
00:07:58,077 --> 00:07:59,207
KIRBY: Hey.
168
00:07:59,278 --> 00:08:00,848
CHARLIE: Climatologist
study climate.
169
00:08:00,913 --> 00:08:03,053
And you might be
thinking, weather?
170
00:08:03,115 --> 00:08:04,775
Climate? What's the difference?
171
00:08:04,851 --> 00:08:09,891
Well, climate is basically
just weather averaged over
a long period of time.
172
00:08:09,956 --> 00:08:14,086
While meteorologists
study weather over
a few days or weeks.
173
00:08:14,160 --> 00:08:19,030
Climatologists study
how weather changes
over months, or years,
174
00:08:19,098 --> 00:08:21,028
or millions of years.
175
00:08:21,100 --> 00:08:24,570
They're the ones that track
global weather patterns and
figure out the ways that
176
00:08:24,637 --> 00:08:27,207
humans are affecting
the global climate.
177
00:08:27,273 --> 00:08:31,143
Cool cool, but maybe you're
looking for something
a little bit more extreme.
178
00:08:31,210 --> 00:08:33,350
Meteorologists are
a little passive.
179
00:08:33,412 --> 00:08:35,952
Climatologists are doing
research all the time.
180
00:08:36,015 --> 00:08:38,985
You're looking for an
adrenaline rush, a thrill.
181
00:08:39,051 --> 00:08:41,491
Luckily there's a job
for people like you.
182
00:08:41,554 --> 00:08:42,794
This is Cindy.
183
00:08:42,855 --> 00:08:43,855
KIRBY: Hey.
184
00:08:43,923 --> 00:08:45,363
CHARLIE: She's a
Hurricane Hunter.
185
00:08:45,424 --> 00:08:46,794
That's her
legitimate job title.
186
00:08:46,859 --> 00:08:48,129
KIRBY: That's right.
187
00:08:48,194 --> 00:08:49,664
CHARLIE: As a hurricane hunter,
188
00:08:49,729 --> 00:08:52,729
she flies planes through
actual hurricanes,
189
00:08:52,798 --> 00:08:57,398
carrying radar and computer
equipment, gathering data
to help researchers track
190
00:08:57,470 --> 00:08:59,870
hurricanes and
predict their paths.
191
00:08:59,939 --> 00:09:01,709
But maybe you
don't fly planes.
192
00:09:01,774 --> 00:09:03,844
CHARLIE: Like Bill.
KIRBY: Hello.
193
00:09:03,910 --> 00:09:05,580
CHARLIE: Bill's
a storm chaser.
194
00:09:05,645 --> 00:09:06,705
KIRBY: That's right!
195
00:09:06,779 --> 00:09:08,809
CHARLIE: "Storm Chaser"
is just a title for
anyone who likes
196
00:09:08,881 --> 00:09:12,081
to find, follow or maybe even
photograph extreme weather.
197
00:09:12,151 --> 00:09:13,751
KIRBY: Like me... Bill.
198
00:09:13,819 --> 00:09:18,989
CHARLIE: Like big
thunderstorms, or hurricanes,
or even tornadoes.
199
00:09:19,058 --> 00:09:23,298
Some people do this
because they like taking
pictures of the weather,
200
00:09:23,362 --> 00:09:25,532
or maybe they do their
own research projects,
201
00:09:25,598 --> 00:09:28,368
or maybe they just do it
for the thrill of it.
202
00:09:28,434 --> 00:09:29,674
Oh, what's up Kirb.
Where you been?
203
00:09:29,735 --> 00:09:31,065
KIRBY: Around.
CHARLIE: Cool!
204
00:09:31,137 --> 00:09:33,007
But this still doesn't
answer our question, right?
205
00:09:33,072 --> 00:09:37,012
We know about all the jobs,
but we don't know how to
predict the severe weather.
206
00:09:37,076 --> 00:09:39,106
KIRBY: Like when's the
next tornado gonna hit?
207
00:09:39,178 --> 00:09:40,278
CHARLIE: Or hurricane?
208
00:09:40,346 --> 00:09:42,006
KIRBY: Or the next moonbow?
209
00:09:42,081 --> 00:09:43,421
CHARLIE: Not sure if
they can predict those.
210
00:09:43,482 --> 00:09:45,152
But you guys know what
we're talking, right?
211
00:09:45,217 --> 00:09:47,017
KIRBY: We got to
talk to someone?
212
00:09:47,086 --> 00:09:48,716
CHARLIE: We need some answers.
KIRBY: But no worries.
213
00:09:48,788 --> 00:09:51,218
We know exactly
who to talk to.
214
00:09:51,290 --> 00:09:54,860
Josh and Karen from the Center
for Severe Weather Research.
215
00:09:54,927 --> 00:09:59,867
CHARLIE: So, when we got on
this extreme weather kick, we
decided to give Josh a call.
216
00:09:59,932 --> 00:10:01,572
KIRBY: Hey Josh, it's Kirby!
217
00:10:01,634 --> 00:10:03,404
JOSHUA: Hi Kirb, how
about coming on over?
218
00:10:03,469 --> 00:10:05,139
KIRBY: Perfect! See you in five!
219
00:10:05,204 --> 00:10:06,714
CHARLIE: Boom! That easy.
220
00:10:06,772 --> 00:10:10,812
So, we're off to the Center
for Severe Weather Research to
meet up with Josh and Karen,
221
00:10:10,876 --> 00:10:12,176
you guys wanna come along?
222
00:10:12,244 --> 00:10:13,484
Awesome, we'll
see you in a bit.
223
00:10:13,546 --> 00:10:14,976
KIRBY: See you soon!
224
00:10:15,047 --> 00:10:19,747
Weird but true,
worms rained down on a
schoolyard in Louisiana!
225
00:10:25,191 --> 00:10:26,131
CHARLIE: Hey guys.
226
00:10:26,192 --> 00:10:27,432
You're just in time.
227
00:10:27,493 --> 00:10:30,333
Today Kirby and I are
investigating extreme weather.
228
00:10:30,396 --> 00:10:33,366
Because earlier today,
there was a tornado warning.
229
00:10:33,432 --> 00:10:36,072
KIRBY: But check it
out it kind of looks like
it's clearing up outside.
230
00:10:36,135 --> 00:10:38,065
Perfect. Let's do it!
231
00:10:38,137 --> 00:10:39,367
CHARLIE: Let's roll!
232
00:10:39,438 --> 00:10:42,678
So, we're off to
Boulder Colorado.
233
00:10:42,742 --> 00:10:46,352
Colorado means colored
red in Spanish.
234
00:10:46,412 --> 00:10:51,452
And it's a beautiful
place to check out
wildlife and wild weather.
235
00:10:51,517 --> 00:10:56,187
Boulder is also where you
can find the Center for
Severe Weather Research.
236
00:10:56,255 --> 00:11:01,425
The experts here at the
CSWR study extreme weather
like hurricanes, tornadoes,
237
00:11:01,494 --> 00:11:04,034
and blizzards year-round.
238
00:11:06,766 --> 00:11:08,166
KIRBY: NSF!
239
00:11:08,234 --> 00:11:09,874
-National Science Foundation.
240
00:11:09,935 --> 00:11:11,135
CHARLIE: There ya go...
241
00:11:11,203 --> 00:11:14,473
"Center for Severe
Weather Research", got a
feeling they're in here.
242
00:11:14,540 --> 00:11:16,910
Hello! Hey guys?
243
00:11:16,976 --> 00:11:18,336
Josh? Karen?
244
00:11:18,411 --> 00:11:19,951
Hi, I'm Charlie.
245
00:11:20,012 --> 00:11:20,952
JOSHUA: Hi! Hi!
246
00:11:21,013 --> 00:11:22,113
CHARLIE: Hi Josh.
247
00:11:22,181 --> 00:11:23,221
JOSHUA: Hi.
CHARLIE: Karen.
248
00:11:23,282 --> 00:11:24,682
KAREN: Hi Charlie.
CHARLIE: This is Kirby.
249
00:11:24,750 --> 00:11:25,820
KAREN: Hi nice to meet you.
250
00:11:25,885 --> 00:11:27,815
CHARLIE: Guys Josh and Karen!
Josh and Karen, guys!
251
00:11:27,887 --> 00:11:33,557
Meet Joshua, President
of the CSWR and he's got
three degrees from MIT.
252
00:11:33,626 --> 00:11:39,726
If it's tornado related or
has to do with 100 mile per
hour winds Joshua's your guy.
253
00:11:39,799 --> 00:11:43,599
His favorite weird but
true fact is, that it's nearly
impossible to see a rainbow
254
00:11:43,669 --> 00:11:45,709
in the sky at full noon.
255
00:11:49,041 --> 00:11:50,581
What got you interested
in this stuff?
256
00:11:50,643 --> 00:11:51,683
Why weather?
257
00:11:51,744 --> 00:11:54,614
JOSHUA: Well we're
really interested in
things that aren't known.
258
00:11:54,680 --> 00:11:56,350
So how do tornadoes form?
259
00:11:56,415 --> 00:11:59,445
How do hurricanes
produce severe winds
right at the surface?
260
00:11:59,518 --> 00:12:02,318
There are a lot of
questions about weather
that just aren't known.
261
00:12:02,388 --> 00:12:04,818
CHARLIE: So, have you ever
been inside a tornado before?
262
00:12:04,890 --> 00:12:06,930
KAREN: Inside? A weak tornado.
263
00:12:06,992 --> 00:12:07,962
CHARLIE: Ooh.
264
00:12:08,027 --> 00:12:10,527
JOSHUA: We intercepted
about 200-some
tornadoes with our
265
00:12:10,596 --> 00:12:14,126
program and we've only been hit
maybe two or three times.
266
00:12:14,200 --> 00:12:15,230
CHARLIE: Are you calm?
267
00:12:15,301 --> 00:12:16,241
Are you freakin' out?
268
00:12:16,302 --> 00:12:17,442
Cause I'd be freakin' out.
269
00:12:17,503 --> 00:12:19,043
JOSHUA: Inside a tornado
it's kind of scary.
270
00:12:19,105 --> 00:12:22,735
It's very windy, stuff shaking
around, sometimes things
are hitting rocks or pieces
271
00:12:22,808 --> 00:12:24,508
of buildings, things
like that are hitting.
272
00:12:24,577 --> 00:12:25,747
CHARLIE: Ooh.
273
00:12:25,811 --> 00:12:27,511
JOSHUA: But we've done just
fine, we're reasonably armored
274
00:12:27,580 --> 00:12:28,810
and we stay pretty safe.
275
00:12:28,881 --> 00:12:30,821
CHARLIE: How well can
they predict when a
tornado's gonna hit?
276
00:12:30,883 --> 00:12:33,323
JOSHUA: Some things
we can predict really
well about tornadoes,
277
00:12:33,385 --> 00:12:35,545
but what we don't know
are the precise details.
278
00:12:35,621 --> 00:12:40,261
So, what we're trying to do
with all of our equipment is
understand the differences
279
00:12:40,326 --> 00:12:42,756
between the storms that make
tornadoes and the ones
280
00:12:42,828 --> 00:12:45,098
that don't so we can
forecast them better.
281
00:12:45,164 --> 00:12:49,034
CHARLIE: So, what are
the best conditions
for tornadoes to form?
282
00:12:49,101 --> 00:12:51,371
JOSHUA: So, we need warm
soupy air at the surface.
283
00:12:51,437 --> 00:12:52,397
KIRBY: Yum.
284
00:12:52,471 --> 00:12:53,811
JOSHUA: Soupy,
sweaty, kind of.
285
00:12:53,873 --> 00:12:55,113
KIRBY: Nasty.
286
00:12:55,174 --> 00:12:57,484
JOSHUA: gross day,
you want a gross day,
but that's not enough.
287
00:12:57,543 --> 00:13:01,713
The second conditions is
really important a really
strong jet stream
288
00:13:01,781 --> 00:13:03,281
above that's warm soupy air.
289
00:13:03,349 --> 00:13:06,789
So, you get a thunderstorm
and the jet stream combined
with the winds at the
290
00:13:06,852 --> 00:13:08,692
surface makes that
thunderstorm rotate.
291
00:13:08,754 --> 00:13:09,724
CHARLIE: Hmm.
292
00:13:09,789 --> 00:13:12,259
JOSHUA: and it's a rotating
thunderstorm that's critical,
293
00:13:12,324 --> 00:13:14,094
that's a super cell.
294
00:13:15,027 --> 00:13:19,097
CHARLIE: Soupy air,
jet stream, super
cell, maybe tornado.
295
00:13:19,165 --> 00:13:20,425
KAREN: Steamy weather.
CHARLIE: Steamy weather.
296
00:13:20,499 --> 00:13:22,399
JOSHUA: And then, and then
the mystery ingredient.
297
00:13:22,468 --> 00:13:23,538
CHARLIE: Which is?
JOSHUA: And then tornado.
298
00:13:23,602 --> 00:13:25,142
-Which is what
you're figuring out right?
-Yes, yes.
299
00:13:25,204 --> 00:13:26,644
JOSHUA: That's
right, that's right.
KAREN: Yeah.
300
00:13:26,705 --> 00:13:28,005
JOSHUA: we wanna know
what's the special sauce?
301
00:13:28,073 --> 00:13:29,383
What's the mystery ingredient?
302
00:13:29,441 --> 00:13:30,511
KIRBY: Nice.
303
00:13:30,576 --> 00:13:31,976
JOSHUA: That makes some of
those storms make tornadoes?
304
00:13:32,044 --> 00:13:33,514
We're still looking, we're
still trying to find out.
305
00:13:33,579 --> 00:13:35,479
CHARLIE: Weird but true fact,
the fastest tornado ever
306
00:13:35,548 --> 00:13:38,318
recorded was over
300 miles per hour.
307
00:13:38,384 --> 00:13:41,924
That's faster than
a racecar and Josh was
the one to measure it.
308
00:13:43,455 --> 00:13:47,725
JOSHUA: The average warning
for tornadoes now is about
13 minutes and that's
309
00:13:47,793 --> 00:13:49,233
much better than
it used to be.
310
00:13:49,295 --> 00:13:52,965
What we're working
on is trying to increase the
understanding so that we teach
311
00:13:53,032 --> 00:13:55,572
the people who are making
the future warnings.
312
00:13:55,634 --> 00:13:58,944
CHARLIE: So, when the
tornado warnings happening,
everyone's hunkering down,
313
00:13:59,004 --> 00:14:00,614
you guys are
heading out right?
314
00:14:00,673 --> 00:14:02,413
KAREN: We're hopefully
already out there.
315
00:14:02,474 --> 00:14:03,714
CHARLIE: Oh, you're
hopefully out there.
316
00:14:03,776 --> 00:14:05,336
KAREN: Yeah, we're
already out there.
317
00:14:05,411 --> 00:14:08,151
JOSHUA: If you see us
pull into your driveway
that's a bad sign.
318
00:14:08,214 --> 00:14:11,954
So, we have a whole
bunch of different
kinds of instruments,
319
00:14:12,017 --> 00:14:13,347
which we can show you.
320
00:14:13,419 --> 00:14:14,619
CHARLIE: Yeah.
321
00:14:14,687 --> 00:14:15,687
JOSHUA: That we drop
around the tornadoes.
322
00:14:15,754 --> 00:14:17,594
CHARLIE: Show us the way.
323
00:14:17,656 --> 00:14:19,526
JOSHUA: These are
called tornado pods.
324
00:14:19,592 --> 00:14:23,032
We have about 20
of these and when a
tornado's coming along,
325
00:14:23,095 --> 00:14:25,695
we drive right in
front and we drop them.
326
00:14:25,764 --> 00:14:29,204
Hopefully the tornado
runs them over.
327
00:14:29,268 --> 00:14:34,868
It's pretty stable, the
computer that collects all
the data is inside this box,
328
00:14:34,940 --> 00:14:38,780
which is very tough, and
we measure the wind in the
tornado two different ways.
329
00:14:38,844 --> 00:14:40,854
One just with this
regular blade.
330
00:14:40,913 --> 00:14:45,083
This sonic Anemometer is using
sound waves to measure the
speed of sound in different
331
00:14:45,150 --> 00:14:47,490
directions, kind of like
what a bat puts out.
332
00:14:47,553 --> 00:14:49,693
CHARLIE: Fun science word,
Ami-nometer, which is a.
333
00:14:49,755 --> 00:14:51,215
KIRBY: Nope the Anemometer.
334
00:14:51,290 --> 00:14:54,690
CHARLIE: It's just
a fancy word for a
wind speed measurer.
335
00:14:54,760 --> 00:14:57,930
JOSHUA: And then we have
cameras looking at the debris
flying by in the tornado.
336
00:14:57,997 --> 00:14:59,967
There's the GPS so
we know where it is.
337
00:15:00,032 --> 00:15:04,142
CHARLIE: So how does the
information you gather help
people predict future weather?
338
00:15:04,203 --> 00:15:07,843
JOSHUA: We're trying to
learn more about what's near
the tornadoes and also what's
339
00:15:07,907 --> 00:15:12,177
going on inside
the tornadoes where we
really can't send people.
340
00:15:12,244 --> 00:15:14,784
JOSHUA: So, Karen's
setting up something
that you'll really like.
341
00:15:14,847 --> 00:15:18,147
When we wanna understand
how tornadoes form we need to
know what the temperatures
342
00:15:18,217 --> 00:15:20,187
and humidities are way
above the ground.
343
00:15:20,252 --> 00:15:23,162
So, Karen is beginning to
prepare a weather balloon.
344
00:15:23,222 --> 00:15:24,662
KAREN: Yes hi.
345
00:15:24,723 --> 00:15:28,863
CHARLIE: Karen's a
bonafide expert in all
things wind related.
346
00:15:28,928 --> 00:15:33,198
She's a big fan of chasing
down storms, so if you see
bad weather brewing in Boulder
347
00:15:33,265 --> 00:15:35,695
there's a good chance
Karen's close by.
348
00:15:35,768 --> 00:15:41,008
Karen's favorite weird but
true fact: lightning strikes
men more often than women!
349
00:15:43,909 --> 00:15:45,949
So how high do the
weather balloons go?
350
00:15:46,011 --> 00:15:47,611
KAREN: They go up to
about 60,000 feet.
351
00:15:47,680 --> 00:15:50,120
Telling us what
the temperature's like,
what the winds are like,
352
00:15:50,182 --> 00:15:52,152
and what the moisture is like
through the whole atmosphere.
353
00:15:52,217 --> 00:15:54,547
CHARLIE: So, would they
be able to tell us if a
storm's cooking today?
354
00:15:54,620 --> 00:15:57,120
KAREN: They'll tell us if
it's a good environment
for a storm to form in.
355
00:15:57,189 --> 00:15:59,629
JOSHUA: One really cool
thing about those balloons
is that they go up and up,
356
00:15:59,692 --> 00:16:00,862
the balloon gets
bigger and bigger.
357
00:16:00,926 --> 00:16:01,986
KIRBY: Yeah.
358
00:16:02,061 --> 00:16:03,361
JOSHUA: And bigger and
eventually becomes about
the size of a house
359
00:16:03,429 --> 00:16:04,459
and then it.
360
00:16:04,530 --> 00:16:06,000
KIRBY: Whoa!
CHARLIE: Holy cow.
JOSHUA: Pops!
361
00:16:06,065 --> 00:16:09,495
KAREN: This is you balloon.
CHARLIE: A little dusty.
362
00:16:13,505 --> 00:16:15,065
KIRBY: Oh man.
363
00:16:15,140 --> 00:16:17,410
CHARLIE: Grow. Grow!
364
00:16:17,476 --> 00:16:19,446
JOSHUA: Just keep
a grip on it.
365
00:16:19,511 --> 00:16:24,451
KIRBY: Its filling up with
tons and tons of helium
until it gets massive enough
366
00:16:24,516 --> 00:16:27,686
to fly up into space.
367
00:16:29,788 --> 00:16:31,888
CHARLIE: This thing's
going up 60,000 feet.
368
00:16:31,957 --> 00:16:34,187
We're measuring
temperature, humidity.
369
00:16:34,259 --> 00:16:35,589
KIRBY: Wind speed.
CHARLIE: Wind speed.
370
00:16:35,661 --> 00:16:37,761
Are we doing this? Ready?
371
00:16:37,830 --> 00:16:38,930
KIRBY: Ready.
CHARLIE: Ready?
372
00:16:38,998 --> 00:16:40,098
KIRBY: Let's do it.
373
00:16:40,165 --> 00:16:41,595
CHARLIE: Alright ready go!
374
00:16:41,667 --> 00:16:43,337
KIRBY: Oh man!
CHARLIE: Woo!
375
00:16:43,402 --> 00:16:45,442
KIRBY: That thing is moving.
376
00:16:47,172 --> 00:16:50,242
Weird but true, the largest
known hailstone in the US,
377
00:16:50,309 --> 00:16:52,479
was about the size
of a soccer ball.
378
00:17:02,488 --> 00:17:04,058
CHARLIE: So, what
are we seeing here?
379
00:17:04,123 --> 00:17:06,593
KAREN: We're looking at
the data from the weather
balloon you just launched.
380
00:17:06,658 --> 00:17:08,688
So, this blue line here that's
your temperature profile.
381
00:17:08,761 --> 00:17:09,761
CHARLIE: Mhm.
382
00:17:09,828 --> 00:17:11,058
KAREN: So as your
balloons going up,
383
00:17:11,130 --> 00:17:12,630
you're seeing that the
temperature is
decreasing with height.
384
00:17:12,698 --> 00:17:15,068
And it seems like it hit a
real moist layer there, so
that's probably the cloud.
385
00:17:15,134 --> 00:17:16,604
CHARLIE: How long do you
usually track 'em for?
386
00:17:16,668 --> 00:17:19,638
KAREN: It depends on the
project I can track them
basically until they burst.
387
00:17:19,705 --> 00:17:23,835
CHARLIE: Oh man guys launching
our very own weather balloon.
388
00:17:23,909 --> 00:17:25,939
I think there's no way we're
topping that one today.
389
00:17:26,011 --> 00:17:28,511
KAREN: Oh, we're going to top
that so prepare to be amazed
390
00:17:28,580 --> 00:17:30,520
and come see the
Doppler on wheels.
391
00:17:30,582 --> 00:17:31,952
CHARLIE: Doppler on wheels?
KAREN: Yes.
392
00:17:32,017 --> 00:17:33,817
CHARLIE: Let's check it out.
KAREN: Yeah!
393
00:17:35,187 --> 00:17:36,957
-Whoa!
394
00:17:37,022 --> 00:17:38,992
KIRBY: Let's go.
CHARLIE: Let's go.
395
00:17:39,058 --> 00:17:40,858
KAREN: This is the
Doppler on wheels.
396
00:17:40,926 --> 00:17:42,556
CHARLIE: It's huge!
KAREN: It is huge.
397
00:17:42,628 --> 00:17:45,898
So even though the truck
is really cool, what's really
cool is the radar in the back.
398
00:17:45,964 --> 00:17:47,074
CHARLIE: Yeah?
399
00:17:47,132 --> 00:17:48,772
KAREN: So, we take this up to
severe weather to study
400
00:17:48,834 --> 00:17:51,004
tornadoes and hurricanes
to really study what's
going on inside.
401
00:17:51,070 --> 00:17:52,000
KIRBY: So cool.
402
00:17:52,071 --> 00:17:53,671
CHARLIE: Can we
take it for a spin?
403
00:17:53,739 --> 00:17:55,039
KAREN: We can.
CHARLIE: Yeah.
404
00:17:55,107 --> 00:17:56,377
KAREN: Yeah come on in.
CHARLIE: Right now? Let's go!
405
00:18:00,079 --> 00:18:03,019
Right now, we're in their
mobile research vehicle
406
00:18:03,082 --> 00:18:06,352
to see how they go
chase thunderstorms.
407
00:18:06,418 --> 00:18:08,648
I think we're heading
in the right direction.
408
00:18:14,159 --> 00:18:19,159
Once we know a storm's coming,
we throw down the hydraulics,
we fire up the transmitters.
409
00:18:19,231 --> 00:18:23,441
Start the radar spinning,
raise the mast and we're
ready to get some data.
410
00:18:23,502 --> 00:18:26,342
Alright Josh, looks like
the Doppler on wheels
is ready to go right?
411
00:18:26,405 --> 00:18:29,675
JOSHUA: We're parked on
the top of the hill we have
good visibility all around,
412
00:18:29,741 --> 00:18:32,311
we have the radar on and
scanning and we're watching
413
00:18:32,377 --> 00:18:34,447
to see if new storms
are developing.
414
00:18:34,513 --> 00:18:36,583
CHARLIE: That's a
lot to control, does
it ever go haywire?
415
00:18:36,648 --> 00:18:40,588
JOSHUA: When we're out there
on a very fast paced mission
trying to chase the tornadoes,
416
00:18:40,652 --> 00:18:42,522
we're coordinating what
other teams are doing.
417
00:18:42,588 --> 00:18:43,858
CHARLIE: Dropping pods.
418
00:18:43,922 --> 00:18:45,322
JOSHUA: Sometimes teams are
launching weather balloons,
419
00:18:45,390 --> 00:18:46,630
it's a lot to keep track of.
420
00:18:46,692 --> 00:18:47,792
CHARLIE: Jeez.
421
00:18:47,860 --> 00:18:49,390
JOSHUA: We don't want anybody
hurt so we're trying to keep
422
00:18:49,461 --> 00:18:50,901
people just out of harm's way
423
00:18:50,963 --> 00:18:53,333
and that's what we
stay focused on in this
mission control truck.
424
00:18:53,398 --> 00:18:55,628
CHARLIE: You're getting
as much data as possible,
but everyone's good to go.
425
00:18:55,701 --> 00:18:57,301
JOSHUA: Yes.
426
00:18:57,369 --> 00:19:00,639
CHARLIE: So, we're back
in the Doppler on wheels
and this is the weather.
427
00:19:00,706 --> 00:19:02,336
That's happening outside
right, now right?
428
00:19:02,407 --> 00:19:05,337
JOSHUA: We're watching
some rain showers that
are over the mountains,
429
00:19:05,410 --> 00:19:06,950
so we can track them here.
430
00:19:07,012 --> 00:19:11,582
The green and bluer areas are
areas where it's raining,
when it gets to be yellow
431
00:19:11,650 --> 00:19:14,250
and pink again, that's when
it's really hard or hail.
432
00:19:14,319 --> 00:19:15,389
CHARLIE: Where...
433
00:19:15,454 --> 00:19:17,124
KIRBY: How far away
can this thing reach?
434
00:19:17,189 --> 00:19:18,659
JOSHUA: Sometimes we can
see 100 miles away,
435
00:19:18,724 --> 00:19:20,994
right now we are
looking about 40 miles.
436
00:19:21,059 --> 00:19:23,459
Some of these cells are
maybe about 20,
437
00:19:23,529 --> 00:19:26,029
25 miles away and they're kind
of moving in our direction.
438
00:19:26,098 --> 00:19:28,898
So right now, we're in
the storm waiting mode,
439
00:19:28,967 --> 00:19:32,037
getting ready to go into that
storm chasing mode.
440
00:19:32,104 --> 00:19:35,544
CHARLIE: So hopefully it
starts heading towards
us fingers crossed.
441
00:19:35,607 --> 00:19:37,907
Alright so I'm sure most of
you think that storm chasing
442
00:19:37,976 --> 00:19:39,846
is really high intensity stuff.
443
00:19:39,912 --> 00:19:43,652
You're being thrashed around
by tornadoes all over the
place and that's what it is
444
00:19:43,715 --> 00:19:48,585
like sometimes, but
most of the time,
445
00:19:48,654 --> 00:19:52,094
storm chasing is kind of
more like storm waiting.
446
00:19:58,030 --> 00:20:00,000
Yo you think we should
check the radar?
447
00:20:00,065 --> 00:20:03,135
KIRBY: Yeah probably.
I'll go do it.
448
00:20:03,202 --> 00:20:04,502
CHARLIE: Alright.
449
00:20:11,210 --> 00:20:14,380
KIRBY: We got a uh storm
coming hot over to the west.
450
00:20:14,446 --> 00:20:18,076
JOSHUA: It's a little
cool outside, the sun's
starting to go down.
451
00:20:18,150 --> 00:20:21,320
Today is probably not a
great day for severe weather.
452
00:20:23,822 --> 00:20:26,792
CHARLIE: Alright guys so
unfortunately, we didn't
see any storms today,
453
00:20:26,858 --> 00:20:29,828
but that's alright cause
we figured out how the
actual scientists
454
00:20:29,895 --> 00:20:31,355
do their storm chasing.
455
00:20:31,430 --> 00:20:34,770
We gotta kick it back to
HQ super quickly because we're
almost running out of time
456
00:20:34,833 --> 00:20:38,573
and I'm sure Josh and
Karen have a lot of super
important research to do.
457
00:20:38,637 --> 00:20:40,567
Hold tight we'll
see you real soon.
458
00:20:44,142 --> 00:20:47,482
KIRBY: Weird but true,
bolts of lightning can shoot
out of an erupting volcano!
459
00:20:52,718 --> 00:20:54,748
Definitely cooler
than a moonbow.
460
00:20:54,820 --> 00:20:56,320
CHARLIE: I don't know man.
KIRBY: Oh, hey guys.
461
00:20:56,388 --> 00:20:57,458
CHARLIE: Hey what's up?
462
00:20:57,522 --> 00:20:59,892
We just got back
from the CSWR.
463
00:20:59,958 --> 00:21:02,788
KIRBY: The Center for
Severe Weather Research.
464
00:21:02,861 --> 00:21:04,961
CHARLIE: Ready. Go!
KIRBY: Oh man!
465
00:21:05,030 --> 00:21:06,160
CHARLIE: Woo!
466
00:21:06,231 --> 00:21:08,931
We saw all of Josh and
Karen's storm weather
chasing equipment.
467
00:21:09,001 --> 00:21:10,841
KIRBY: It was crazy cool!
468
00:21:10,902 --> 00:21:12,702
CHARLIE: So, we pretty much
have it figured out right?
469
00:21:12,771 --> 00:21:14,611
How to predict
these tornadoes.
470
00:21:14,673 --> 00:21:16,383
What else did we learn today?
471
00:21:16,441 --> 00:21:18,281
There were so many
weird but true things.
472
00:21:18,343 --> 00:21:24,753
A tropical storm becomes a
hurricane when wind speeds
hit 74 miles per hour.
473
00:21:25,183 --> 00:21:29,153
An anemometer is a
tool that can measure the
wind speeds of a tornado.
474
00:21:29,221 --> 00:21:33,791
Hurricane hunters
fly planes through
hurricanes to study them.
475
00:21:35,260 --> 00:21:36,830
Hey guys it looks
pretty clear outside.
476
00:21:36,895 --> 00:21:38,455
Maybe we can go to the beach!
477
00:21:38,530 --> 00:21:39,670
KIRBY: Perfect!
478
00:21:39,731 --> 00:21:41,731
You go grab the beach stuff,
I'll double check the weather.
479
00:21:41,800 --> 00:21:42,900
CHARLIE: Cool, cool.
480
00:21:42,968 --> 00:21:44,738
KIRBY: No storms,
we're looking good.
481
00:21:44,803 --> 00:21:48,513
CHARLIE: Alright, whoa, whoa,
whoa, whoa, you see that
storm system over Moline?
482
00:21:48,573 --> 00:21:51,113
Forget the beach stuff we
gotta go chase this storm.
483
00:21:51,176 --> 00:21:52,336
KIRBY: Let's do it.
484
00:21:52,411 --> 00:21:55,051
CHARLIE: Alright guys
we gotta go, but stop
by again when we
485
00:21:55,113 --> 00:21:57,023
discover more things
that are weird but true.
486
00:21:57,082 --> 00:21:58,552
KIRBY: Alright check it out.
