Spatial and temporal distribution of precipitation in the Vosges mountain range area
Minářová, Jana ; Müller, Miloslav (advisor) ; Šmídová, Jana (referee)
Spatial and temporal distribution of precipitation in the Vosges mountain range area Abstract The aim of this work is to study the climatology of atmospheric precipitation in the studied area situated in the Northeastern France. Factors, e.g. the global circulation of the atmosphere, that influence the spatial and temporal distribution of precipitation in the mid-latitudes, especially in Western Europe and in mountainous regions, are discussed from the macro- to micro- scale in the first part. The term "ombric continentality" is clarified and a description of the physical geography of the studied area is performed, e.g. upward and windward asymmetry of Vosges slopes and contrasts between the mountain range and the Upper Rhine Plain. Secondly a demonstration is made that the Vosges mountain range affects, due to its position, the spatio-temporal distribution of precipitation at a regional scale. This is carried out by computing the daily rainfall on 14 meteorological stations out of the period 1951-2011. Three categories of stations were determined according to their annual precipitation repartition: (i) mountain stations with the winter precipitation maximum, (ii) leeward slope stations with two precipitation maxima, i.e. in winter and summer and (iii) leeward stations located in the Upper Rhine Plain East...

Character of precipitation during the last 200 years in Prague Klementinum and their impact on water management in the landscape
Střeštík, Jaroslav
The course of the annual precipitation displays no change over 200 years, only a very slow decline during the 20th century, particularly in its second half. The same, just a little stronger trend holds true for the number of days in each year with abundant precipitation and for percentage of annual precipitation in these days. Therefore, more and more water falls during weak rains instead of the richer ones, which is not favorable for agriculture, because more water evaporates shortly after the rain. In the same period, water flows in major rivers increase, or very little decrease, although precipitation totals are falling more rapidly. Therefore, the proportion of water flowing into the sea is increasing and the proportion remaining in the landscape decreases. All these factors contribute to an intermittent water shortages and an increasing risk of drought occurrence.

The temperature and precipitation course in Prague-Karlov, 1961-2010
Střeštík, Jaroslav
The course of temperatures and precipitation in Prague over the last 50 years is presented and compared with scenarios of the further development of the climate. The temperature increased significantly and this increase is more rapid than that of the global temperature. Precipitation totals display only very small decrease over the last 50 years. However, precipitation totals in spring decreased more than the annual sums and a remarkable decrease of days with heavy rainfall takes place. These facts contribute to the observed decrease of the amount of moisture in nature and to the increased occurrence of droughts. There is no indication that all these observed trends could be different in future.
