Abstract

The paper analyses the occurrence of thunderstorms in Bydgoszcz in the multi-annual period 1971–2010 based on data from the Bydgoszcz-Airport weather station – ref. EPBY according to ICAO (International Civil Aviation Organization). The article examines variations in monthly, seasonal and annual mean values of weather elements. The calculation pertaining to selected elements of descriptive statistics involved regression analysis. Based on the linear function the author determines the direction and trends of changes of the analysed elements in time. Analysis of this data leads to the conclusion that the number of thunderstorms in the examined forty-year period declined, but also a decrease in the frequency of this phenomenon was observed in Bydgoszcz. The highest number of storms in the examined multi-year period in the whole year (29) and in the warm half-year (28) was recorded in 1973 and in 1997, and the lowest in 2003 (only 6). The studies indicate a significant downward trend in the number of storms occurring in the multi-annual period 1971-2010.
