Typical synoptic situations for thunderstormy days observed over the majority of Poland, and with the highest probability of thunderstorms occurence in the country

Abstract

[EN]In the present study, we have performed an analysis of synoptic situations in thunderstorm days, during which the thunderstorm phenomenon was noted at at least 80% of meteorological stations located in Poland or at which the probability of an occurrence of days with this phenomenon was the highest and whose frequency explains the occurrence of days with thunderstorms on the highest level. The analysis of synoptic maps from the period 1951-2000 made the isolation of two different synoptic situations characteristic for days with thunderstorms occurring over the entire area of Poland possible. As well two synoptic situation with the highest probability of thunderstorms occurrence and which frequency explains the best the occurrence of days with thunderstorms have been distinguished.

[ES]En este estudio realizamos un análisis de las situaciones sinopticas en dias de tormenta, definidas como aquellas que aparecen en al menos el 80% de los observatorios meteorológicos polacos o en que la probabilidad de un acontecimiento de días con este fenómeno era la más alta y cuya frecuencia explica el acontecimiento de días con tormentas al mayor nivel. El análisis de mapas sinópticos a partir del período 1951-2000 permitió el aislamiento de dos situaciones sinópticas características de días con tormentas que ocurren sobre el conjunto de Polonia. También se han identificado dos situación sinópticas con la mayor probabilidad de ocurrencia de tormentas y cuya frecuencia explica el mejor el acontecimiento de días con tormentas.
