00:00:00.000 --> 00:00:01.961
Here’s a question,

2
00:00:01.966 --> 00:00:09.533
How does a group of satellites, each no more than a foot long, help improve forecasts for tropical storms and hurricanes?

3
00:00:09.533 --> 00:00:10.600
Let's take a look.

4
00:00:11.433 --> 00:00:15.700
Hurricanes are some of the most powerful and destructive weather events on Earth.

5
00:00:16.233 --> 00:00:24.000
The 2020 Atlantic hurricane season was one of the most brutal on record, producing a record-breaking 30 named storms.

6
00:00:24.700 --> 00:00:29.566
What’s more, a record-tying 10 of those storms were characterized as rapidly intensifying,

7
00:00:29.566 --> 00:00:34.066
some throttling up by 100 miles per hour in under two days.

8
00:00:34.400 --> 00:00:39.400
Many weather satellites will generally measure a storm only once every few hours,


9
00:00:39.400 --> 00:00:42.900
leaving gaps in coverage where a storm may quickly strengthen.


10
00:00:44.085 --> 00:00:48.288
To help fill this observation gap, NASA is launching TROPICS;

11
00:00:48.590 --> 00:00:54.759
a collection of 6 small satellites designed to make a big impact on our understanding of damaging storms.

12
00:00:55.566 --> 00:01:02.700
Their mission: to provide near-hourly observations of a storm's precipitation, temperature, and humidity,

13
00:01:02.700 --> 00:01:06.966
allowing scientists to better understand what drives a storm’s intensification.


14
00:01:07.466 --> 00:01:13.533
To achieve this, researchers at MIT’s Lincoln Laboratory developed a miniaturized microwave radiometer

15
00:01:13.533 --> 00:01:16.300
that’s about the size of a cup of coffee.

16
00:01:16.300 --> 00:01:24.566
This small instrument will measure storm strength by detecting the thermal radiation naturally emitted by the oxygen and water vapor in the air.

17
00:01:25.300 --> 00:01:31.566
As Earth’s climate continues to change, cost-effective, but powerful, satellites like TROPICS will be an

18
00:01:31.566 --> 00:01:38.200
important tool to help us better observe developments driving rapid changes in powerful storms.

19
00:01:38.431 --> 00:01:43.459
And help forecasters better predict – and prepare – for the weather ahead.
