1 00:00:42,420 --> 00:00:40,020 since I was a kid I've always been 2 00:00:45,390 --> 00:00:42,430 interested in storms as an engineer I 3 00:00:47,340 --> 00:00:45,400 try to understand how things work so I 4 00:00:49,890 --> 00:00:47,350 actually built and designed a device to 5 00:00:56,190 --> 00:00:49,900 measure the weather basically on the 6 00:00:58,979 --> 00:00:56,200 inside of a tornado the United States on 7 00:01:01,470 --> 00:00:58,989 average gets about 1200 tornadoes per 8 00:01:03,840 --> 00:01:01,480 year and the reason is is because of its 9 00:01:05,969 --> 00:01:03,850 unique geographic location 10 00:01:08,400 --> 00:01:05,979 we got the Gulf of Mexico off to the 11 00:01:11,010 --> 00:01:08,410 south and the storm systems as they pass 12 00:01:12,660 --> 00:01:11,020 through draw this Gulf moisture as water 13 00:01:15,060 --> 00:01:12,670 vapor it comes right up through the 14 00:01:16,710 --> 00:01:15,070 Midwest and springtime generally 15 00:01:19,920 --> 00:01:16,720 reflects it very what we call a very 16 00:01:22,499 --> 00:01:19,930 active jet stream and it brings us very 17 00:01:25,650 --> 00:01:22,509 powerful winds that just comes right 18 00:01:27,510 --> 00:01:25,660 across the Midwest that in combination 19 00:01:28,950 --> 00:01:27,520 allows these big storm systems to 20 00:01:32,510 --> 00:01:28,960 develop and of course wind shear is a 21 00:01:35,850 --> 00:01:32,520 very powerful ingredient for tornadoes 22 00:01:37,890 --> 00:01:35,860 the ingredients for a tornado obviously 23 00:01:39,990 --> 00:01:37,900 are quite complex but some of the basics 24 00:01:41,969 --> 00:01:40,000 are you don't have to have moisture you 25 00:01:44,100 --> 00:01:41,979 have to have lift and then the most 26 00:01:47,310 --> 00:01:44,110 other most important ingredient is what 27 00:01:49,680 --> 00:01:47,320 they call wind shear and shear creates 28 00:01:51,450 --> 00:01:49,690 these big horizontal rolls in the 29 00:01:53,940 --> 00:01:51,460 atmosphere and then when a thunderstorm 30 00:01:55,980 --> 00:01:53,950 forms underneath it actually tip sees 31 00:01:58,740 --> 00:01:55,990 these horizontal rolls in the vertical 32 00:02:00,179 --> 00:01:58,750 position to where a thunderstorm forms 33 00:02:02,760 --> 00:02:00,189 over them you have the whole 34 00:02:05,910 --> 00:02:02,770 thunderstorm rotating those final 35 00:02:08,190 --> 00:02:05,920 processes are what we're trying to study 36 00:02:10,350 --> 00:02:08,200 you know what's bringing the rotation 37 00:02:11,729 --> 00:02:10,360 finally all the way to the ground and 38 00:02:15,090 --> 00:02:11,739 that's really one of the biggest 39 00:02:16,979 --> 00:02:15,100 mysteries of tornado formation you know 40 00:02:18,690 --> 00:02:16,989 it's very difficult to forecast where 28 41 00:02:20,280 --> 00:02:18,700 it's gonna be when we're actually in the 42 00:02:22,440 --> 00:02:20,290 field waiting for thunderstorms to 43 00:02:24,420 --> 00:02:22,450 develop we use what they call visible 44 00:02:26,910 --> 00:02:24,430 satellite imagery this is basically a 45 00:02:28,890 --> 00:02:26,920 picture from space showing the best 46 00:02:31,979 --> 00:02:28,900 areas what we call instability and 47 00:02:34,170 --> 00:02:31,989 that's how and where we are able to 48 00:02:36,270 --> 00:02:34,180 target these storms that are developing 49 00:02:39,050 --> 00:02:36,280 ground-based radar can't even see these 50 00:02:41,850 --> 00:02:39,060 storms develop but satellite can 51 00:02:42,910 --> 00:02:41,860 satellites also detect what we call 52 00:02:48,160 --> 00:02:42,920 bound 53 00:02:49,600 --> 00:02:48,170 thunderstorms become the focus of new 54 00:02:52,380 --> 00:02:49,610 thunderstorms during the day and 55 00:02:55,000 --> 00:02:52,390 actually enhance the tornado potential 56 00:02:57,640 --> 00:02:55,010 visible satellite technology allows us 57 00:02:59,680 --> 00:02:57,650 to identify this which otherwise would 58 00:03:03,520 --> 00:02:59,690 be going totally unnoticed and 59 00:03:05,260 --> 00:03:03,530 undetected one of the biggest things 60 00:03:07,930 --> 00:03:05,270 that I would love to see in future 61 00:03:10,449 --> 00:03:07,940 satellite technology is the ability to 62 00:03:12,730 --> 00:03:10,459 actually see lightning within the cloud 63 00:03:14,830 --> 00:03:12,740 tops all the vertical motions so forth 64 00:03:17,500 --> 00:03:14,840 greatly enhances its ability to create 65 00:03:19,510 --> 00:03:17,510 lightning this lightning mapping will 66 00:03:21,130 --> 00:03:19,520 actually show frequency if the storm is 67 00:03:24,040 --> 00:03:21,140 becoming severe the lightning frequency 68 00:03:25,720 --> 00:03:24,050 increases and thus be able to do an 69 00:03:35,260 --> 00:03:25,730 early detection of whether or not that 70 00:03:37,960 --> 00:03:35,270 storm is severe or not if we knew more 71 00:03:39,100 --> 00:03:37,970 about tornado Genesis and structure and 72 00:03:40,900 --> 00:03:39,110 we're able to stretch that warning out 73 00:03:43,660 --> 00:03:40,910 to 20 or 25 minutes right now the 74 00:03:45,850 --> 00:03:43,670 average time is about 15 minutes or so 75 00:03:48,460 --> 00:03:45,860 that gives people more time to prepare 76 00:03:50,140 --> 00:03:48,470 and seek shelter without the ghost 77 00:03:52,600 --> 00:03:50,150 satellite we would be back in the dark 78 00:03:54,789 --> 00:03:52,610 ages of the mid to early 60's these 79 00:03:56,770 --> 00:03:54,799 ghost satellites are responsible in my
