Prevention of destructive tropical and extratropical storms , hurricanes , tornadoes , dangerous thunderstorms , and catastrophic
Tropical cyclones and storms, hurricanes, powerful thunderclouds, which generate tornadoes, destructive ex-tratropical cyclones, which result in catastrophic floods, are the powerful cloud systems that contain huge amount of water. According to the hypothesis argued in this paper, an electric field coupled with powerful clouds and electric forces play a cardinal role in supporting this huge mas...
متن کاملTweeting and tornadoes
Social Media and micro-blogging is being used during crisis events to provide live up-to-date information as events evolve (before, during and after). Messages are posted by citizens or public officials. To understand the effectiveness of these messages, we examined the content of geo-located Twitter messages (“tweets”) sent during the Moore, Oklahoma tornado of May 20, 2013 (+/-1day) to explor...
متن کاملForecasting Tornadoes in Georgia
Some climatological data on the seasonal, diurnal, and geographical distribut>iorl of tornadoes in Georgia are presented, and the tornado "season" is defined as occurring from February through April. Twelve different storms producing t,ornadoes during one or more 12-hour forecast periods are studied for synoptic similarities. A mean tornado sounding and a 700-mb. composite chart, taken from dat...
متن کاملPhysically-Based Simulation of Tornadoes
In this paper, we present a physically-based model to perform 3D visual simulation of tornadoes. Simulating natural phenomena based on physically realistic models has been an active research area in computer graphics. The tornado phenomenon is a spectacular one as it demonstrates the magnificent strength of forces of nature and its shear size. Previous research on tornadoes have focused either ...
متن کاملBoundary-layer Decoupling Affects on Tornadoes
The North American low-level jet is known to have substantial impacts on the climatology of central and eastern regions of the United States. However, the development of the low-level jet may also have an impact on the low-level shear, which could rapidly alter an environment toward becoming more favorable for producing tornadoes. This study investigates this mechanism’s contribution to enhanci...
