00:00:04.240 --> 00:00:09.240
Huffman: The monsoon is a seasonal rain and wind pattern that was first described over

3
00:00:09.240 --> 00:00:13.259
south Asia. You see the clouds blossoming here during the summer part of

4
00:00:13.259 --> 00:00:18.240
the monsoon. For centuries people have known about it, but only recently have we

5
00:00:18.240 --> 00:00:22.520
received enough data from satellites to really describe what's going on.

6
00:00:22.520 --> 00:00:27.800
Skofronick-Jackson: What you can see here is moist air that has evaporated from the ocean, coming across

7
00:00:27.800 --> 00:00:32.740
India and providing rainfall, driving the monsoon season.

8
00:00:32.740 --> 00:00:38.180
Huffman: One really cool way to look at the monsoon is to do a split-screen and look at the summer and the

9
00:00:38.190 --> 00:00:43.320
winter at the same time. In the summer the wind is blowing onshore, bringing the

10
00:00:43.320 --> 00:00:49.040
moist rain-laden air into the continent. In the winter time, it blows off the continent.

11
00:00:49.040 --> 00:00:52.559
Skofronick-Jackson: Now those winds are basically driven by temperature differences

12
00:00:52.559 --> 00:00:58.079
between the ocean and the land. And where the land is nice and warm, the air

13
00:00:58.079 --> 00:01:02.879
expands and it draws in the moist air from the ocean waters, but in the

14
00:01:02.879 --> 00:01:07.650
winter time it's very cold. The moisture then it goes from the continent back

15
00:01:07.650 --> 00:01:11.590
into the oceans. Having a better understanding of the

16
00:01:11.590 --> 00:01:16.450
global water cycle and monitoring changes over time is important for

17
00:01:16.450 --> 00:01:22.290
society, for our everyday lives and our long-term future.
