00:00:02.850 --> 00:00:06.750
In 2020, there were a record 30
named hurricanes in the

2
00:00:06.750 --> 00:00:07.350
Atlantic.

3
00:00:08.519 --> 00:00:11.159
Hurricanes occur in the warmer
months when the ocean

4
00:00:11.159 --> 00:00:15.539
temperature rises.

5
00:00:13.049 --> 00:00:15.877
NASA monitors and tracks
hurricanes through

6
00:00:15.943 --> 00:00:19.430
Earth-Observing satellites. These

7
00:00:19.496 --> 00:00:23.246
instruments allow NASA to see
things like the movement of

8
00:00:23.311 --> 00:00:27.127
storms at night, rainfall rates,
surface wind speed, cloud

9
00:00:27.193 --> 00:00:29.430
heights, ocean heat, and humidity.

10
00:00:30.810 --> 00:00:34.800
All the data collected is free
and accessible to the public, so

11
00:00:34.800 --> 00:00:38.430
regional and local governments
as well as federal agencies like

12
00:00:38.430 --> 00:00:42.150
FEMA can better prepare for
hurricanes in advance, leading

13
00:00:42.150 --> 00:00:44.190
to more efficient relief action.

14
00:00:46.410 --> 00:00:50.670
NASA also tracks the long term
changes of hurricanes. As human

15
00:00:50.670 --> 00:00:53.700
caused climate change appears to
be strengthening the strongest

16
00:00:53.700 --> 00:00:57.840
storms. More storms are
increasing in strength within a

17
00:00:57.840 --> 00:01:00.810
24-hour period. which is a
process called rapid

18
00:01:00.810 --> 00:01:06.660
intensification. In 2020, a
record-tying nine storms rapidl

19
00:01:06.660 --> 00:01:07.500
intensified

20
00:01:10.500 --> 00:01:13.770
NASA has developed a machine
learning model that could more

21
00:01:13.770 --> 00:01:17.460
accurately detect rapidly
intensifying storms, with the

22
00:01:17.460 --> 00:01:20.940
goal of giving people more time
to prepare for high intensity

23
00:01:20.940 --> 00:01:22.080
storms and flooding.

24
00:01:23.910 --> 00:01:26.850
In addition to rapid
intensification, storms are

25
00:01:26.850 --> 00:01:31.050
stalling, or moving forward mor
slowly, making them mor

26
00:01:31.050 --> 00:01:31.800
destructive

27
00:01:33.300 --> 00:01:36.360
These hurricanes can slow to
just a few miles an hour,

28
00:01:36.660 --> 00:01:40.380
dumping rain and fierce winds on
one location at a time.

29
00:01:44.490 --> 00:01:48.300
Using satellites NASA also helps
to assess the aftermath of

30
00:01:48.300 --> 00:01:53.490
storms. In 2020, NASA's
Disasters program provided data

31
00:01:53.490 --> 00:01:58.680
to groups in Alabama, Louisiana,
and Central America to identify

32
00:01:58.680 --> 00:02:02.340
regions significantly affected
by hurricanes, like which

33
00:02:02.340 --> 00:02:06.330
neighborhoods remain dark with
no power. This helps to both

34
00:02:06.330 --> 00:02:10.110
identify vulnerable communities
and make informed decisions

35
00:02:10.110 --> 00:02:11.970
about where to send resources.

36
00:02:16.110 --> 00:02:20.370
Hurricanes can displace entire
cities of people whose homes or

37
00:02:20.370 --> 00:02:23.670
neighborhoods are destroyed and
cause millions of dollars worth

38
00:02:23.670 --> 00:02:24.930
f damage every year.

39
00:02:26.190 --> 00:02:29.130
In addition to on-the-ground
relief, it's important to

40
00:02:29.130 --> 00:02:32.820
continue to monitor hurricane
behavior and characteristics so

41
00:02:32.820 --> 00:02:35.940
that weather models can more
accurately predict the magnitude

42
00:02:35.970 --> 00:02:37.560
and trajectory of storms.

43
00:02:41.070 --> 00:02:44.280
When it comes to hurricanes, our
eyes in the sky can provide

44
00:02:44.280 --> 00:02:47.580
critical data to help keep
people in the know and out of

45
00:02:47.580 --> 00:02:48.300
harm's way.
