摘要：Abstract The results from a comprehensive drought analysis for the entire Slovakia based on the precipitation records at a large number of climatic stations (491) over a considerable span of time (33 years) are presented. The study included the definition of homogenous regions regarding the temporal pattern of the droughts (by means of Principal Components Analysis, PCA), the analysis of the frequency of the droughts (based on the Kernel occurrence rate estimation method, KORE, coupled with bootstrap confidence bands) and the definition of minimum precipitation surfaces aiming at the recognition of the drought events at the early stages of their occurrence. .
