Tweeting 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...
متن کاملPrecipitation, the Rear Flank Downdraft, and Tornadoes
1. INTRODUCTION Because of the apparent importance of dynamic and thermodynamic properties of RFDs to tornadogenesis, these are studied for a variety of prescribed environments using a 1.5-dimension downdraft model. The spatial dimensionality of this model is purposely less than three so as to simplify analyses and to focus on vertical processes, which are thought to be of primary importance. M...
