Abstract

The present study is an illustrated version of the Abstract of a PhD Theses prepared by the first author at the University of Szeged". The aim of the Theses is to give a modem climatographical analysis on the varied hydrometeorological relations of the region, based on reliable observations of meteorological stations. The analysis includes statistical characteristics of the inter-annual variability, spatial and temporal correlation of the available soil moisture content and long-range changes, as well as their possible relation with climatic trends for greater regions. The above-mentioned aims are intended to be realised on the basis of the Palmer's Drought Severity Index (PDSI) data series. Monthly PDSI data series of five stations (Miskolc, Nyíregyháza, Debrecen, Kecskemét and Szeged) were determined for the 20th century, in three versions. To study the spatial correlations short PDSI sets of 17 stations were calculated for the period between 1951 and 1992, with Thornthwaite's plant-independent method and without homogenisation. The objective and results of our work is to help further the inter-disciplinary study of agro-ecological problems, influenced by the soil moisture content, by performing objective regionalization based on soil moisture anomalies in the region; by publishing the characteristics and the calendar of the objective yeartypes; and also by determining climatically representative, long dry and wet periods.
