The influence of climate conditions on the intensity and spreading of wind erosion was considered in forthe area of Southern Moravia, Czech Republic. For this purpose, 16 climatological climatology stations were selected on the basis of the accessibility to the of required data, their adequate representativeness and homogeneity of the data, homogeneity, and locationsituation of the stations. It was necessary to make tThe database of climatological climatology factors (such ase.g. wind velocity, precipitation, and air temperature) for in the period between 1961 and 2003 was developed for the analyses of climatological data. The climatological data was then evaluated for the periods of 1961–2003, 1961–1990, 1991–2000, and 1971–2000. The Cclimatic erosion factor, which explains potential erodibility of soil by wind, was determined through the analyses of factors influencing the wind erosion. The assessment of the influence of expected climate change on the intensity and spreading of wind erosion includedconsists in the selection of suitable climatological model and climate change scenarios on the basedis onf the ability to model the three climatological factors (wind velocity, precipitation, and air temperature). Climate change scenarios were then applied onto the data fromof the selected climatological stations, and the assessment of changes in data sets, and the comparative analysis of the scenario outputs of the scenarios with measured data from the normal period of 1961–1990 were done. The climatic erosion factor was also determined from the altered scenario data of the scenarios.
