Abstract

This paper presents the results of an objective analysis, which deals with thunderstorm-climatology. The aim of this study is twofold: firstly, to describe the space and time distribution of severe thunderstorms in Hungary using radar data in the five-year period of 2003-2007, and secondly, to analyze the relationship between severe thunderstorms and macrosynoptic circulation types. We have applied. Péczely's (1957) synoptic circulation types. The core of the examination is the modified TITAN (Thunderstorm Identification, Tracking, Analysis, and Nowcasting)-method (Dixon and Wiener, 1993), where thunderstorms are represented with ellipses (thunderstorm-ellipses). Severe and highly severe thunderstorm-ellipses and stormy days are defined. Most of the severe and highly severe stormy days were associated with typical synoptic situations: prefrontal warm sectors of active cyclones, cold fronts, and anticyclone edges. The detected thunderstorm-ellipses had maxima in the south-west, north, and east parts of Hungary. The results of this examination may be important for forecasting severe thunderstorms, so damage and loss can be reduced.
