The purpose of this work is a detailed description of spring precipitation totals in the Czech Republic, which has not been examined in more detail yet. The main aims of the diploma thesis are i) comparison of precipitation characteristics at individual stations for the period 1984-2014 and analysis of temporal and spatial variability of precipitation, ii) division of stations into three categories (lowland stations, stations in middle positions, mountain stations) based on altitude, average spring total precipitation and surrounding relief, and iii) division of stations by cluster analysis and comparison of precipitation characteristics between individual categories of stations obtained by subjective and objective methods. Statistical and precipitation characteristics include monthly and seasonal precipitation total, numbers of wet and dry days, numbers of days with a total above 5,10,15, and 20 mm, frequency and length of dry and wet periods, index of torrential rainfall and trends of these characteristics. The results show increasing linear trends of spring precipitation totals in all station categories, however these trends are statistically insignificant. The driest stations are lowland stations with an average spring precipitation total of 139,3 mm, the highest median of 169 dry periods, and...
