Warunki opadowe na stacji meteorologicznej Ursynów SGGW w latach 1960-2009

In this paper, monthly precipitation sums, measured at Ursynów WULS – SGGW station in the period 1960–2009 were analysed. The coeffi cient of the variability of yearly precipitation sums was calculated and the linear trend of yearly precipitation sums was examined. The method of Kaczorowska (1962) was applied to classify months and years in respect of precipitation quantity. A detailed analysis was performed also on daily maximum precipitation sums for years 1980–2009. The probability of maximum daily precipitation occurrence was calculated for various intervals of the precipitation and for different seasons of the year.
