【 摘 要 】

Determination of maximum gust in convection storms. Many times when storm damage occurs mainly in summer in buildings, trees or other objects, people automatically say it was a tornado! Although it is difficult for many to understand that currents descendants wind from can cause the large damage and occur frequently in the summer months. Storm winds from can exceed 110 km/h. Although most wind speeds out of the storms from 54 to 90 km/h, occasionally they may exceed 110 km/h. Storms which produce such wind gusts are, generally, identified later, so meteorology warnings are difficult issued. As a result of these causes were sought techniques by which we can quickly determine the degree of danger and to anticipate the evolution of cloudy formation which has the capacity to develop dangerous wind gusts. Convective wind speed was estimated using the relationship VIL – ET (vertically integrated liquid –echo Top) from data from weather radar WSR-98D from the Bobohalma, as exemplified in a few extreme situations.
