WEBVTT FILE 1 00:00:02.399 --> 00:00:05.911 On February 3, scientists boarded a NASA flight headed 2 00:00:05.976 --> 00:00:09.879 straight first snowstorm the kind of weather both pilots and 3 00:00:09.944 --> 00:00:13.782 passengers typically like to avoid. But this flight was all 4 00:00:13.847 --> 00:00:17.490 in the name of science, specifically the IMPACTS mission 5 00:00:17.555 --> 00:00:21.653 or investigation of microphysics and precipitation for Atlantic 6 00:00:21.718 --> 00:00:25.686 Coast threatening snowstorms. The team is tracking snowstorms 7 00:00:25.751 --> 00:00:29.199 across the Midwest and eastern United States with two 8 00:00:29.264 --> 00:00:33.297 aircrafts, a P3 equipped with multiple instruments operated by 9 00:00:33.362 --> 00:00:37.460 scientists and a high altitude flying ER-2 crewed by one pilot. 10 00:00:37.525 --> 00:00:41.038 They're looking to better understand the formation and 11 00:00:41.103 --> 00:00:42.990 development of winter storms. 12 00:00:44.610 --> 00:00:48.767 So our goal is to observe and measure winter storms that 13 00:00:48.841 --> 00:00:53.369 mostly that happen along the east coast of the United States. 14 00:00:53.443 --> 00:00:57.675 On this specific flight we are flying over a really major 15 00:00:57.749 --> 00:01:02.351 winter storm that is affecting the Midwest as well as tomorrow 16 00:01:02.426 --> 00:01:04.950 is going to go into the Northeast. 17 00:01:07.980 --> 00:01:11.088 Ultimately, what the impacts team learns about snowstorms 18 00:01:11.143 --> 00:01:14.252 will improve meteorological models and our ability to use 19 00:01:14.306 --> 00:01:17.579 satellite data to predict how much snow will fall and where. 20 00:01:23.310 --> 00:01:26.383 For today's flight it's been almost unnervingly smooth so far 21 00:01:26.434 --> 00:01:29.457 at all altitudes. We're dealing with a lot of crosswinds and 22 00:01:29.507 --> 00:01:32.581 changing winds, particularly as we move up and down the track 23 00:01:32.631 --> 00:01:33.690 across the frontline. 24 00:01:36.359 --> 00:01:40.156 The inflight team members work in conjunction with ground 25 00:01:40.222 --> 00:01:43.886 operations, monitoring, changing weather conditions and 26 00:01:43.953 --> 00:01:47.816 coordinating flight paths with the other aircraft. On this 27 00:01:47.883 --> 00:01:51.746 flight, the P3 flew a total of eight hours flying the same 28 00:01:51.813 --> 00:01:55.876 200-mile stretch of snowstorm three times each at a different 29 00:01:55.943 --> 00:02:00.540 elevation in order to capture data from precipitation as it descends. 30 00:02:01.920 --> 00:02:06.704 Especially in turbulent cloud, turbulent storm, ice particles 31 00:02:06.783 --> 00:02:10.940 that form at certain temperatures, certain altitudes. 32 00:02:11.018 --> 00:02:14.862 So right now we're actually seeing a lot of plate 33 00:02:14.940 --> 00:02:19.803 aggregates. So we have a lot of not individual plates that I'm 34 00:02:19.881 --> 00:02:23.490 seeing but mostly just large plate aggregates. 35 00:02:25.500 --> 00:02:29.040 The multi year impacts campaign is the first comprehensive study 36 00:02:29.070 --> 00:02:32.670 of snowstorms across the eastern United States in 30 years.
