1 00:00:01,040 --> 00:00:05,020 [pulsing music plays] 2 00:00:05,040 --> 00:00:09,020 Norcross: A hurricane is mother nature's grandest, but most ferocious weather machine. 3 00:00:09,040 --> 00:00:13,020 Sullivan: A hurricane is two different things. If you're looking at it from above 4 00:00:13,040 --> 00:00:17,020 from the satellite down, a hurricane is a beautiful thing. 5 00:00:17,040 --> 00:00:20,980 It's a massive coil of clouds that is rotating, spinning like a top. 6 00:00:21,000 --> 00:00:25,020 Sims: When I look at images of hurricanes, I go through 7 00:00:25,040 --> 00:00:29,020 so many emotions. As a scientist, as a meteorologist, 8 00:00:29,040 --> 00:00:33,020 I'm like, "Wow, this is fascinating. 9 00:00:33,040 --> 00:00:36,980 You know, look at this beautiful storm. 10 00:00:37,000 --> 00:00:40,980 [sound of waves and wind] But then the human side of me is saying, 11 00:00:41,000 --> 00:00:44,980 "How can we make sure that people are evacuating, that people have somewhere to stay, 12 00:00:45,000 --> 00:00:48,980 that they have the money to feed their families once they leave their homes?" 13 00:00:49,000 --> 00:00:52,980 Sullivan: A hurricane on the ground 14 00:00:53,000 --> 00:00:56,980 that's a completely different thing, because all of that rotation 15 00:00:57,000 --> 00:01:00,980 you really feel as incredibly severe winds. 16 00:01:01,000 --> 00:01:04,980 They can be up to 150 or more miles per hour. 17 00:01:05,000 --> 00:01:08,980 You can have up to 40 inches of rain and the most deadly thing 18 00:01:09,000 --> 00:01:12,980 is that the updraft from the hurricane is actually pulling ocean swell 19 00:01:13,000 --> 00:01:16,980 up into it and so it creates a storm surge. 20 00:01:17,000 --> 00:01:21,020 up to 40 feet high 21 00:01:21,040 --> 00:01:25,020 DeMaria: And occasionally when the storms hit at a little higher latitude, 22 00:01:25,040 --> 00:01:29,020 , they can also spawn tornadoes in their fringe. 23 00:01:29,040 --> 00:01:33,020 So really the impacts are the wind, the storm surge, the heavy rainfall, 24 00:01:33,040 --> 00:01:37,020 and then occasionally severe weather that forms when they move inland. 25 00:01:37,040 --> 00:01:41,020 Sullivan: I feel like I got a deeper appreciation for hurricanes when I moved 26 00:01:41,040 --> 00:01:45,020 to Galveston, Texas.That entire city, 27 00:01:45,040 --> 00:01:49,020 it's almost like the ghosts of the 1900 hurricane … are still there 28 00:01:49,040 --> 00:01:52,980 because you see evidence of that storm, that particular 29 00:01:53,000 --> 00:01:56,980 famous storm that killed somewhere between 6,000 and 12,000 people. 30 00:01:57,000 --> 00:02:01,020 And so that is a very present thing in the city 31 00:02:01,040 --> 00:02:05,020 even to this day. 32 00:02:05,040 --> 00:02:08,980 Kirschbaum: That was a category four storm that hit Galveston 33 00:02:09,000 --> 00:02:13,020 on September 8th and there really was not a lot of information about 34 00:02:13,040 --> 00:02:17,020 what was happening in the Caribbean before the storm made landfall. 35 00:02:17,040 --> 00:02:20,980 Mandt: And the hurricane hit them totally unprepared 36 00:02:21,000 --> 00:02:24,980 and thousands of people lost their lives. 37 00:02:25,000 --> 00:02:29,020 Tremendous damage because it surprised everyone. 38 00:02:29,040 --> 00:02:33,020 With the onsets of satellites, that will never happen. 39 00:02:33,040 --> 00:02:37,020 Kim: The first leap forward would have been being able to see 40 00:02:37,040 --> 00:02:41,020 the entire planet from space in the first place. 41 00:02:41,040 --> 00:02:45,020 Prior to that, how would you know, for example, that a hurricane was coming? 42 00:02:45,040 --> 00:02:49,020 It would have been very difficult to know where it was coming, where it was going, 43 00:02:49,040 --> 00:02:53,020 how bad it was going to be. 44 00:02:53,040 --> 00:02:57,020 Mandt: So, that's one of the dramatic impacts, is satellite data … sort of like, 45 00:02:57,040 --> 00:03:01,020 your eyes in the sky to make sure that mother nature never can surprise you. 46 00:03:01,040 --> 00:03:05,020 Sims: When I was a child, I loved playing with magnifying glasses 47 00:03:05,040 --> 00:03:09,020 because you can zoom in and see so many fine details. And that's what we can do 48 00:03:09,040 --> 00:03:13,020 with the satellites that we have now, particularly the GOES-R series. 49 00:03:13,040 --> 00:03:17,020 We're getting 60 times more data now than what we were in the previous series. 50 00:03:17,040 --> 00:03:21,020 Sullivan: You know, the first satellites I worked with, the GOES-I through M, 51 00:03:21,040 --> 00:03:24,980 which were great satellites, but taking a picture of a globe every 25 minutes 52 00:03:25,000 --> 00:03:29,020 you know the hurricanes would be here. And then they're here and then they're here. 53 00:03:29,040 --> 00:03:33,020 And it's not like you're losing track of them. But the difference between that 54 00:03:33,040 --> 00:03:37,020 and being able to see, oh, it's swerving. It's curling. Oh, it's dying. 55 00:03:37,040 --> 00:03:41,020 We take a full disc picture of the entire hemisphere 56 00:03:41,040 --> 00:03:45,020 in five minutes. But we can also look at smaller areas. 57 00:03:45,040 --> 00:03:49,020 And you can scan that once every 30 seconds. You get to see 58 00:03:49,040 --> 00:03:53,020 as the hurricane eye wall was forming, you can see that actually forming in real time. 59 00:03:53,040 --> 00:03:57,020 The Earth looks alive … it looks like a living thing. 60 00:03:57,040 --> 00:04:01,020 [shimmering music] 61 00:04:01,040 --> 00:04:05,020 Mandt: So the polar orbiting satellites complement the geostationary, 62 00:04:05,040 --> 00:04:09,020 , since a geostationary like 24,000 miles up. 63 00:04:09,040 --> 00:04:13,020 While they get great pictures, it's really hard to measure 64 00:04:13,040 --> 00:04:17,020 what is the state of the atmosphere from that distance. 65 00:04:17,040 --> 00:04:21,020 So the polar orbiting are basically flying at little over 500 miles up. 66 00:04:21,040 --> 00:04:24,980 And when you're at that altitude you can sense 67 00:04:25,000 --> 00:04:28,980 what's in the atmosphere to a lot higher resolution. 68 00:04:29,000 --> 00:04:32,980 The JPSS satellite, is really, primary purpose 69 00:04:33,000 --> 00:04:36,980 is to take measurements of the temperature and moisture of the atmosphere 70 00:04:37,000 --> 00:04:40,980 to drive the weather forecast models. 71 00:04:41,000 --> 00:04:44,980 Kim: Two things that people always want to know about hurricanes 72 00:04:45,000 --> 00:04:48,980 are how strong is it, and where is it going to hit? 73 00:04:49,000 --> 00:04:52,980 And microwave sounders can certainly help with both of those. 74 00:04:53,000 --> 00:04:56,980 The ability to see through clouds becomes really important. 75 00:04:57,000 --> 00:05:00,980 If you've ever seen a picture of a hurricane from space, 76 00:05:01,000 --> 00:05:04,980 mostly what you're seeing is clouds. 77 00:05:05,000 --> 00:05:08,980 And you can get a better weather forecast, a better prediction of how strong the hurricane is 78 00:05:09,000 --> 00:05:12,980 and where it's going to hit, which direction it's going to go, if you could see through those clouds 79 00:05:13,000 --> 00:05:16,980 and see the structure of the atmosphere; maybe even the ocean conditions underneath that. 80 00:05:17,000 --> 00:05:20,980 And so microwave sensors allow you to do that kind of thing. 81 00:05:21,000 --> 00:05:24,980 Mandt: As you've seen, when they do the 82 00:05:25,000 --> 00:05:28,980 there's usually a cone of uncertainty they put in the path. 83 00:05:29,000 --> 00:05:32,980 We don't know exactly where it's going, but for the next three days 84 00:05:33,000 --> 00:05:36,980 or five days or seven days, here's the cone that it could go in. 85 00:05:37,000 --> 00:05:40,980 But you don't want to over-warn, right? 86 00:05:41,000 --> 00:05:44,980 You don't want to have the whole East Coast run in inland a hundred miles 87 00:05:45,000 --> 00:05:48,980 because of a hurricane, potential hurricane. 88 00:05:49,000 --> 00:05:52,980 You'd like that as precise as you can, so that only the people who are really going to be affected have to do something. 89 00:05:53,000 --> 00:05:56,980 The improved sensors that we've been flying 90 00:05:57,000 --> 00:06:00,980 allow a better understanding of the core of that hurricane 91 00:06:01,000 --> 00:06:04,980 and allow the forecasters to better predict precisely 92 00:06:05,000 --> 00:06:08,980 where that hurricane is going to hit. And when they do that 93 00:06:09,000 --> 00:06:12,980 then you can narrow and shrink that cone of uncertainty and give a better prediction. 94 00:06:13,000 --> 00:06:16,980 DeMaria: We hope to continue to improve the ability to do track forecasting. 95 00:06:17,000 --> 00:06:20,980 That's gotten so much better over the past couple of decades. 96 00:06:21,000 --> 00:06:24,980 Our five-day forecast is about as accurate as our two-day forecast 97 00:06:25,000 --> 00:06:28,980 was only about 20 years ago. 98 00:06:29,000 --> 00:06:32,980 Porter: And increasingly, people are listening 99 00:06:33,000 --> 00:06:36,980 to the forecast that they get from meteorologists. They have increased confidence, 100 00:06:37,000 --> 00:06:40,980 , they see the improvement in forecasts as it relates to hurricanes over the last couple of decades. 101 00:06:41,000 --> 00:06:44,980 And when a hurricane watch or hurricane warning goes into effect 102 00:06:45,000 --> 00:06:48,980 people take notice and they take action. And that's really encouraging to see. 103 00:06:49,000 --> 00:06:52,980 [music fades] 104 00:06:53,000 --> 00:06:57,793
