The effect of relief on the distribution of atmospheric precipitation in Slovakia in the southern cyclonic situations This article is focused on identifying windward and leeward places in the territory of Slovakia during southern cyclonic situations. These places arise due to relief that affects the distribution of precipitation by altitude and orientation to southern flow. Southern flows are an important source of moisture for southern Slovakia. Based on precipitation sums of all the rainfall gauges during the days with the southern cyclonic situations the precipitation fields were interpolated for the period 1991-2017. Using the created windward index, windward and leeward places on precipitation fields were mapped out. Based on the map outputs, the effect of the relief was analyzed on the wettest and driest places. It was found out that the most rainfall falls in the mountains in the southern part of central Slovakia. The results were compared with the predictions ALADIN and the ECMWF models and the precipitation field from the selected synoptic situation. The achieved results have been confirmed. Research results have practical uses in several areas, particularly in meteorology, hydrology and agriculture.
