There certainly have been significant science and technology improvements in recent decades that pay dividends with events such as this.<br /><br />That said, if the goal is to reduce the loss of life and injury, non-science/technology factors (i.e., human nature) are surely a significant part of the problem, and I would argue, the bulk of the problem.<br /><br />I believe tornado fatalities can be reduced to essentially zero in 20 years, much as U.S. Commercial Aviation fatalities are essentially zero now -- something unthinkable 20 years ago.<br /><br />To reach that goal will take much more than better observational and modeling systems. Those interested might find this as a good discussion starting point:<br /><br />http://nwas.org/meetings/abstracts/display.php?id=1414<br /><br />http://nwas.org/meetings/nwa2012/presentations/NWA2012_P2.52_Zeitler.zipAnonymoushttps://www.blogger.com/profile/07503975751335795185noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-38068045277392482722013-05-22T09:37:52.301-07:002013-05-22T09:37:52.301-07:00Since the Gov't falls behind onroviding the co...Since the Gov't falls behind onroviding the computer power, how about doing the idea that the radio-astronomers did, and harnessing the power of networked private computers?<br /><br />The Gov't could even encourage this by offering tax relief to those willing to pungle up the extra bucks to upgrade their computer purchases to more powerful machines, and their networking throughput to higher levels.

The initial warning for this tornado was ...Cliff, <br /><br />The initial warning for this tornado was originally issued at 240. Then the warning and tornado emergency that you cite at 3:01. I made a similar oversight yesterday as well. Thus, the warnings on this event were first given with very long lead time.

I've had an idea for a theoretical tornado defense system, but don't know if the energy required would come even close. Perhaps you have some insight into whether I'm even remotely close...<br /><br />In a nutshell, the idea would be to bury rows of huge tanks of compressed liquid air in strips of vacant land or farmland along the edge of town where a tornado might start to rip through a town.<br /><br />The system would have funnel-cloud detectors of some sort, and right when a funnel cloud passes over a section of tanks, the tanks would explosively release the liquid air into the funnel-cloud, hopefully helping to quench the thermal updrafts and disrupt the funnel formation.<br /><br />Any thoughts on this theoretical system? I'm guessing that the scales of tanks required would be far too huge, but perhaps you might have some additional insight. <br /><br />Thanks again for your always-excellent weather reporting and analysis!<br /><br />-Clintslinkyhttps://www.blogger.com/profile/04979717118198492341noreply@blogger.com
