dc.description.abstract | Seasonal trends in extreme precipitation indices were investigated for 30 yr moving
periods between December 1950 and February 2008. To update the 2008 to 2015 data, supplementary
calculations were performed for >120 meteorological stations. A linear regression of the
least squares method was used to calculate trend magnitudes. Trend significance was tested using
the Mann-Kendall method. Changes in short-term trend frequency and temporal coherence were
assessed. Extreme precipitation was defined as a daily amount exceeding the 95th percentile, calculated
separately for each month and station using daily totals ≥1 mm. The spatial pattern of
extreme precipitation trends varied by season. Significant extreme precipitation trends were rare,
constituting approximately 25 to 30% of all analysed trends, and were seldom temporally coherent.
Most of these significant trends were upward, except in summer, when a nearly equal frequency
of positive and negative trends was found. Increases in the frequency and the total were a
characteristic feature of extreme precipitation changes, particularly in winter. Seasonal variations
in the spatial patterns of extreme precipitation trends may have resulted from seasonal changes in
the prominence of the driving factors of precipitation. In spring, upward trends in Central and
Western Europe were twice as frequent as the downward trends found primarily in Southern
Europe. In summer, the percentages of significant downward trends in Western Europe and
upward trends in Eastern Europe were similar. In autumn, a coherent decrease in extreme precipitation
was clear in Central Europe. The spatial distribution of trend directions was the most
consistent in winter. | pl_PL |
