Extreme precipitation events in the Czech Republic in the context of climate change

摘要

As an introduction, short survey of two analyses of long-term fluctuationsof annual precipitation totals in the Czech Republic is presented. The mainfocus of this paper is to contribute to investigation of precipitationtrends in the Czech Republic by another point of view. For every pixel of1 km2 size, annual maxima of daily precipitation were obtained for timeperiod of 112 years (1895–2006). Based on these time series, we were tryingto answer question if there are some changes of area size/distribution ofannual maximum of daily precipitation totals. Courses and trends areanalyzed for some parameters of area distribution of annual maximum of dailyprecipitation totals in the area of the Czech Republic. No significantclimate changes of tested precipitation characteristics were found.
