ABSRACT. – Changes in the Carpathian Basin droughts frequency in the last three hundred years. Examining the last three hundred years data (1710 and 2009) on droughts in the Carpathian Basin, approximately every second year was droughty, and it was severe drought, reaching serious proportions, on average, every tenth year. The frequency and intensity of droughts, more specifically the relative frequency, in the studied ten sub-periods varies surprisingly significantly: between 26% and 61%. Although the frequency of droughty years ,in the second half of the study period, decreased slightly, studying combined the droughts intensity and frequency the most droughty period was between 1983 and 2009, in which the serious and the extremely severe droughts reached approximately 30% incidence. This is a serious warning signal for the future, because depending on the climate change in the future this could become even worse.
