especially strong wind or if you found
00:01:03
yourself in a blizzard or a downpour or
00:01:06
if you've ever heard thunder or seen
00:01:09
lightning well that
00:01:11
means you're in
00:01:15
a
00:01:19
storm storms happen all over the world
00:01:22
every day without storm life wouldn't be
00:01:25
anything like the way we know it the
00:01:27
world's dir and water wouldn't be nearly
00:01:29
as f

[Music]
00:01:58
help
00:02:05
uh

00:02:12
W get all
00:02:28
this
00:02:34
[Applause]
00:02:37
oh I'll get you my little science
00:02:46
man
00:02:51
oh storms are extreme
00:02:55
[Music]
00:02:58
weather
00:03:01
they're caused by the heat of the
00:03:05
sun water in the
00:03:08
air and the spin of the
00:03:13
Earth take a look at
00:03:16
this it's our miniature gigantic extreme
00:03:19
storm system simulator of science now
00:03:22
when the sun is out like during the day
00:03:24
it heats up the surface of the Earth as
00:03:27
simulated by these red lamps that makes
00:03:29
the air near the ground get warm then
00:03:31
cooler air from surrounding areas flows
00:03:33
in and forces the warm air way up like
00:03:38
this now way up it's a lot cooler cuz
00:03:41
it's closer to space so we get this flow
00:03:43
of air moving up and down at the same
00:03:46
time these are the conditions that make
00:03:48
storms now we're simulating a lot of
00:03:51
sunlight over an enormous area of land
00:03:53
with huge masses of air now in real life
00:03:56
the air Flows In from different
00:03:58
directions so it can start to spin like
00:04:01
this wherever you've got heat an
00:04:04
atmosphere and a spinning Planet it
00:04:07
really turns things up storms are
00:04:12
extreme weather extreme

you this has been extreme weather
00:05:17

00:05:32
baby they'll soak you
00:05:35
[Music]
00:05:50
[Music]
00:05:55
rotten from time to time a mysterious
00:05:58
thing occurs over the Eastern Pacific it
00:06:00
affects the weather worldwide it is El
00:06:07
Nino
00:06:12
ELO normally trade winds blow over this
00:06:15
part of the ocean keeping it cool but
00:06:17
from time to time it stops then the Sun
00:06:21
beats down warming the sea which warms
00:06:24
the air and no one knows why it is elino
00:06:32
[Music]
00:06:37
El when this happens fish die fish
00:06:42
die and storms rage all over the
00:06:50
globe it is El
00:06:54
Nino
00:06:55
ELO now I must
00:06:58
go
00:07:00
00:07:08
Amigos
00:07:16
El unseasonably warm and stormy weather
00:07:19
we're having at this time of year don't
00:07:20
you
00:07:21
think this strange weather phenomenon my
00:07:24
friend is the work of none other than
00:07:28
El
00:07:30
El
00:07:33
Nino El
00:07:37
Nino a mysteriously warm area of water
00:07:40
in the Pacific it can affect World
00:07:42
weather patterns causing unseasonably
00:07:44
warm weather and more frequent and
00:07:47
Powerful
00:07:49
storms
00:07:55
El on planet Earth there are storms the
00:07:58
size of Texas hurricanes and typhoons
00:08:02
they're formed when huge areas of the
00:08:04
open ocean soak up a tremendous amount
00:08:06
of heat from the
00:08:07
Sun cool air squeezes warm air up the
00:08:11
warm air carries water vapor with it
00:08:13
when the vapor turns back into a liquid
00:08:14
when it rains it releases a lot of
00:08:16
energy high in the atmosphere which
00:08:18
helps Drive The Winds of the storm these
00:08:21
storms are so big that they get spun by
00:08:24
the Spin of the
00:08:28
Earth more energy being released every
00:08:30
second from a dozen atom
00:08:32
bombs now the winds are moving so fast
00:08:35
that these storms end up with a hollow
00:08:37
spot right in the middle called the eye
00:08:39
of the storm the winds are calm there
00:08:42
while they're really howling around the
00:08:43
outside now if one of these storms moves
00:08:45
from the ocean onto the land they can
00:08:47
really tear things
00:08:51
[Music]
00:08:58
upoh
00:09:02
when I call their Mass meets a hot one
00:09:04
look out
00:09:05
baby it's
00:09:14
storic hey there aren't any anchovies on
00:09:16
this menu what's that all
00:09:19
about oh no
00:09:23
[Music]
00:09:26
not the missing fishies my young friend
00:09:29
are the result of mysteriously warm
00:09:31
Waters killing creatures like your
00:09:34
precious anchovies from Alaska to Peru
00:09:38
it is none other
00:09:40
than El
00:09:42
[Music]
00:09:51
n lightning is electricity the flow of
00:09:55
electrons now let's say that these
00:09:56
people are
00:09:57
electrons they're all negative they have
00:10:00
the same charge so they're repelling
00:10:01
each other right now there's nowhere for
00:10:04
them to go but when the door
00:10:06
[Music]
00:10:11
opens they spread
00:10:16
out the same thing happens in clouds
00:10:19
let's say this is a cloud and this
00:10:21
rubber belt is keeping a chalk full of
00:10:22
electrons now they'll spread out if we
00:10:24
let
00:10:25
them they spread
00:10:28
out
00:10:30
the easiest way for them to do that is
00:10:31
to find a path to the ground like this
00:10:34
oh no it's a big dark stormcloud coming
00:10:36
our way quick everyone get in the
00:10:40
house
00:10:42
pow a bolt of
00:10:45
lightning how about
00:10:47
lightning heats up the air and makes it
00:10:49
expand so fast it's like an
00:10:52
explosion Thunder and thunder can get
00:10:55
pretty
00:10:57
loud see we were going to make my bones
00:10:59
light up like in the cartoons but
00:11:02
instead we went with this makeup
00:11:15
effect when you're caught in a
00:11:17
thunderstorm a tree may look like a nice
00:11:18
shelter but it's
00:11:21
not since lightning strikes to the
00:11:24
highest point around a tree is a prime
00:11:27
target
00:11:30
so don't stand under a tree during a
00:11:32
thunderstorm what you should do is get
00:11:34
short and make as little contact with
00:11:36
the ground as possible so the
00:11:38
electricity is less likely to choose you
00:11:40
as a path than say if you were under a
00:11:42
tree or standing in the field or lying
00:11:44
flat so just squat like this and let the
00:11:46
lightning find something else to hit you
00:11:48
may feel a little uncomfortable but it
00:11:50
beats getting
00:11:52
[Music]
00:11:57
Zapped
00:12:04
good
00:12:06
[Applause]
00:12:07
one I bet those kids downstairs are
00:12:10
shaking in their
00:12:11
shoes you know whenever Angels go
00:12:14
bowling we make thunder no we don't we
00:12:17
don't no Thunder is caused when charges
00:12:20
due to static electricity are built up
00:12:22
in the clouds on the surface of the
00:12:23
planet when the difference in the charge
00:12:25
is big
00:12:26
enough you get a bolt of lightning that
00:12:28
instantly heats the air up to five times
00:12:30
the temperature of the Sun that creates
00:12:32
a sound wave known as
00:12:34
Thunder would G all this time I thought
00:12:38
my 710 splits were the cause of
00:12:40
explosive
00:12:42
sound well they're sure going to get a
00:12:44
rainstorm down there
00:12:47
huh I'm going to cry and when Angels Cry
00:12:51
The Rains
00:12:52
come about that rain thing we need to
00:12:57
talk
00:13:01
it's a
00:13:03
twister tornadoes take place when air
00:13:06
masses of extremely different
00:13:07
temperatures come together see the sun
00:13:11
shines right through the air and warms
00:13:12
the land the land acts like a stove and
00:13:15
heats the air above it now instead of
00:13:17
the hot air getting squeezed and Rising
00:13:20
it's held down by a slab of cold air so
00:13:22
if conditions are right the hot air
00:13:24
punches a hole through the cold air and
00:13:26
rushes up through it like a bathtub
00:13:28
drain upside down if that happens take
00:13:31
cover my friends you got yourself a
00:13:35
twister when that happens my friend take
00:13:38
cover cuz you got yourself a
00:13:40
[Music]
00:13:49
[Music]
00:13:54
twister some storm spin because of the
00:13:56
Earth's
00:13:57
rotation oh behave you little
00:14:04
[Music]
00:14:13
twister the stuff we have here is our
00:14:16
most recent area of research and it
00:14:18
involves work at the University of
00:14:19
Colorado to model tornadoes in the
00:14:21
laboratory we chose water because Water
00:14:24
and Air Act the same way you can work
00:14:26
with either one of them and get good
00:14:27
results we disc that some of these lab
00:14:29
tornadoes make very very loud
00:14:34
sounds and we're trying to understand
00:14:36
that because we've discovered that
00:14:38
fullblown tornadoes in the atmosphere
00:14:40
also make sounds but when we deal with
00:14:42
real tornadoes the sound we're expecting
00:14:44
is going to be so low that we require an
00:14:46
electronic ear to hear it this is our
00:14:49
electronic ear all of these hoses that
00:14:51
are going out from it like an octopuses
00:14:53
technicals are the sensing element that
00:14:55
all feed in to this uh microphone
00:14:59
all storms are really potentially
00:15:01
dangerous in some way but we might be
00:15:03
able to listen to sounds that could save
00:15:07
lives you can see how a tornado works
00:15:10
just fill up two 2 L pop bottles these
00:15:12
plastic ones are cool
00:15:14
because you can do that so have a
00:15:17
so-called friend help you fill up the
00:15:24
[Music]
00:15:27
bottles
00:15:30
[Music]
00:15:42
now have a friend help you empty the
00:15:44
bottles make it AAS tip the bottles over
00:15:46
at the same time keep one bottle steady
00:15:48
and give the other one a twirl ready
00:15:50
okay
00:15:54
go see when you get it spinning the
00:15:56
water drains much faster the same same
00:15:58
thing happens with cornado when air gets
00:16:00
spinning it spins faster and faster to
00:16:02
make a wild spinning
00:16:08
[Music]
00:16:10
stor I
00:16:13
won the Earth isn't the only place with
00:16:15
storms no they happen all over the solar
00:16:18
system this is the planet Jupiter it's
00:16:20
over 1,300 times the size of the Earth
00:16:24
and for hundreds of years astronomers
00:16:26
have observed a great spot it's a storm
00:16:29
a
00:16:30
hurricane and it's over twice the size
00:16:33
of our planet it's been raging for
00:16:36
hundreds of years and you're saying why
00:16:38
doesn't it die down the way hurricanes
00:16:39
do on the earth well there's two things
00:16:41
first of all Jupiter is huge Jupiter
00:16:44
twice as large as all the other planets
00:16:45
combined secondly it's spinning very
00:16:48
very fast it takes Jupiter only 10 Earth
00:16:51
hours to go all the way around so the
00:16:53
winds on the surface of Jupiter are
00:16:55
really moving they're going fast enough
00:16:57
to sustain this GI gigantic storm for
00:16:59
centuries on another planet
00:17:09
wow there's the Sun up in theing places
00:17:12
all around at different rates wind
00:17:19
evaporates storming in because cold air
00:17:23
pushes warm air way
00:17:25
up has been falling lately is on the way
00:17:29
and baby we should all get ready baby
00:17:32
here comes a hurricane now we at the
00:17:34
rain is pouring look out cuz the
00:17:36
windowing war and masses blowing it's
00:17:39
all mixing up the
00:17:46
[Music]
00:17:49
atmosphere well that's our show thanks
00:17:51
for watching if you excuse me I've got
00:17:52
some mesocyclone advection currents to
00:17:54
quantify see you produce in association
00:17:57
with the National Science found
00:17:59
going to get right into the lifting
00:18:00
condensation level right on right to the
00:18:01
meter the half meter and that way we'll
00:18:04
know for sure what induce this
00:18:07
blizzard yeah as the air goes up and
00:18:11
then after a while it goes
00:18:14
[Applause]
00:18:17
down I'm buying lunch today in fact I'm
00:18:20
feeling pretty
00:18:21
good I'm buying lunch for
00:18:24
everyone hey
00:18:25
everyone lunch is on me I'll take a STI
