1 00:00:00,100 --> 00:00:04,160 One of the things that's really interesting about snowflakes that not many people know is that 2 00:00:04,180 --> 00:00:08,270 every single one of them has six sides. And that's the way 3 00:00:08,290 --> 00:00:12,390 that the bonds, when they freeze, they actually 4 00:00:12,410 --> 00:00:16,510 force the water to have a fixed side. Liquid 5 00:00:16,530 --> 00:00:20,700 water can move all around, you know, you can pour it and stuff like that, but snow always has 6 00:00:20,720 --> 00:00:24,860 six sides. As the snowflake grows, parts 7 00:00:24,880 --> 00:00:28,900 form off the side depending on the temperature and the water that's 8 00:00:28,920 --> 00:00:32,940 available within the atmospheric column. You start to get 9 00:00:32,960 --> 00:00:37,000 different parts that come out of that snowflake. And you can get these 10 00:00:37,020 --> 00:00:41,070 beautifully complex dendrites with just little 11 00:00:41,090 --> 00:00:45,140 spikes off of them, and they are all from that hard binding 12 00:00:45,160 --> 00:00:49,350 between the oxygen and the hydrogen within 13 00:00:49,370 --> 00:00:53,450 the water itself as it freezes. It's important to be able to 14 00:00:53,470 --> 00:00:57,580 improve these numerical weather predictions and their forecasts. Right 15 00:00:57,600 --> 00:01:01,590 now they're slowly moving toward making the 16 00:01:01,610 --> 00:01:05,660 snowflakes within these models more realistic. And GPM can do 17 00:01:05,680 --> 00:01:09,700 that because we are able to measure layer-by-layer within the storm 18 00:01:09,720 --> 00:01:13,790 and provide drop size distributions, not only of the rain 19 00:01:13,810 --> 00:01:17,860 particles, but also the snowflakes within that storm. 20 00:01:17,880 --> 00:01:22,000 And that allows us to put that information into 21 00:01:22,020 --> 00:01:26,200 numerical weather prediction to have a better estimate of these types of storms 22 00:01:26,220 --> 00:01:30,360 and where they're going to have the most impact on society. 23 00:01:30,380 --> 00:01:34,470 24 00:01:34,490 --> 00:01:37,247
