Extrema dygnsregn och trender i Skåne och på Västkusten / Extreme daily rainfall and trends in Skåne and the west coast
Series of daily precipitation including 89 years from Malmö, Halmstad and Göteborg have been analyzed as well as daily precipitation from 230 stations in Skåne in the period 1961–1990. The distribution in space and time has been investigated, and also the relation between daily rainfall and different parameters. The most extreme
independent events have occurred rather evenly distributed over Skåne, although there is a weak relation between high daily precipitation and annual precipitation. Different frequency distributions have been attempted. The most extreme observed daily precipitation amounts can not be fitted to any statistical frequency distribution. The return period of daily precipitation near 100 mm is very long. Trends have been investigated. It is for the long time series over 89 years not possible to find any trend of changing annual
highest daily precipitation. However, there have been trends over shorter periods.
