Pola opadów w Polsce związane z niżami Vb van Bebbera
Precipitation fields in Poland associated with van Bebber’s Vb cyclones

Summary/Abstract: The article presents the course of the average annual trajectory of van Bebber’s Vb cyclones. The most rainfall-efficient section of the trajectory, i.e. the occurrence region of cyclones which produce the highest precipitation in Poland, was delimited. A map of average daily precipitation totals associated with Vb lows was constructed as well as a map indicating the maximum rainfall i.e. the highest sum of daily precipitation at the weather station in the period 1958‒2008 associated with the Vb cyclones situated close to the most rainfall-efficient segment of the trajectory. Vb route begins at the Balearic Sea and ends over southern Finland. The highest rainfall in Poland is associated with lows situated in the vicinity of the middle section of the trajectory – over eastern Hungary, western Romania or southern Slovakia. The highest average amount of rainfall can be observed in south-eastern Poland, particularly in the Żywiec dale, in the Tatras, and over the Lublin Upland. Maximum daily rainfall associated with Vb cyclones occurred on Śnieżka peak and reached 129.2 mm.
