The Storm Prediction Center (SPC) is developing both a tornadic and severe nontornadic sample of supercell storms from 2014. This latest work is an extension of earlier research which led to the development of conditional probabilities of tornado damage rating from near-storm environment and radar-based storm-scale characteristics from a 5-year sample of tornadoes (4,770) reported in the contig...

The tornado that struck Milwaukee, WI on March 8, 2000 was the earliest on record. Unlike most tornadoes, this particular tornado was not associated with a supercell or any form of a mesocyclone. The author argues that a lake breeze circulation created a misocyclone in the region, which was elongated vertically by a rapidly deepening convective thunderstorm in the region, producing the tornado.

Tornadoes are violently rotating columns of air extending from thunder storms to the ground. While extensive studies have been conducted to assess wind loads and flow structures around building models in strong winds, most of the previous investigations were conducted with straight-line winds. Bienkiewicz and Dudhia (1993) found that the wind loads acting on building models in tornado-like wind...

A database of tornado fatalities, nontornadic convective wind fatalities, severe thunderstorm warnings, and tornado warnings was compiled for the period 1986–2007 to assess the spatial and temporal distribution of warned and unwarned fatalities. The time of fatality and location as reported in StormDatawas compared to tornado and severe thunderstorm warnings to determine if a warning was in eff...

(1) Background: Tornadoes are one of the deadliest disasters but their health impacts in China are poorly investigated. This study aimed to assess the public health risks and impact of an EF-4 tornado outbreak in Funing, China; (2) Methods: A retrospective analysis on the characteristics of tornado-related deaths and injuries was conducted based on the database from the Funing's Center for Dise...

In this paper we describe Tornado, which we teach in our software engineering project courses. Tornado is a new process model that combines the Unified Process with Scrum elements. The Tornado model focuses on scenario-based design starting with visionary scenarios funneling down to demo scenarios. Tornado o↵ers models for a broad range of activities. In addition to formal models used for analy...

OBJECTIVES We analyzed tornado-related injuries seen at hospitals and risk factors for tornado injury, and screened for post-traumatic stress following a statewide tornado-emergency in Alabama in April 2011. METHODS We conducted a chart abstraction of 1,398 patients at 39 hospitals, mapped injured cases, and conducted a case-control telephone survey of 98 injured cases along with 200 uninjure...

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 ...

Present-day operational tornado forecasting can be thought of in two parts: anticipation of tornadic potential in the storm environment, and recognition of tornadic storms once they develop. The former is a forecasting issue, while the latter is associated with warnings (or so-called nowcasting). This paper focuses on the forecasting aspect of tornadoes1, by dealing primarily with the relations...
