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...

S ince the early 1970s, Doppler radar has been used as the primary tool in advancing our knowledge of the kinematics and dynamics of severe convective storms. In particular, a pair of fixed-site, S-band Doppler radars in central Oklahoma was used by the National Severe Storms Laboratory (NSSL) in Norman for a number of years. Based on singleand dualDoppler data collected by the serendipitous ne...

In this paper we present a novel method to generate 3D animation of tornados from video clips taken from a single camera. Our source of input data is a variety of tornado video clips of widely-varying fidelity available on the world wide web. By extracting the silhouette of the foreground figure and using a model-based approach, the problem is reformulated as a local, optimized search of the sh...

BACKGROUND/OBJECTIVE To qualitatively describe interventions by schools to meet children's needs after the May 2011 Joplin, Missouri tornado. METHODS Qualitative exploratory study conducted six months after the tornado. Key informant interviews with school staff (teachers, psychologists, guidance counselor, nurse, principal), public health official, and physicians. REPORT After the tornado,...

The widespread use of GPS-enabled smartphones along with the popularity of micro-blogging and social networking applications, e.g., Twitter and Facebook, has resulted in the generation of huge streams of geo-tagged textual data. Many applications require real-time processing of these streams. For example, location-based e-coupon and ad-targeting systems enable advertisers to register millions o...

On 7 May 2012 between approximately 1500-1600 UTC (45pm BST) a small tornado was reported by a number of observers in Witney, Kidlington and Bicester in Oxfordshire (see White 2012; Jones 2012; many more details and photographs/videos can be found by searching the world wide web). The strong winds associated with this tornado led to damage of trees, roofs and streetlights. Damage site investiga...
