The paper is part of a series earlier studies in which the precipitation enhancement potential in central and northern Greece is assessed. A drought analysis is performed in this study. In particular, the Palmer Drought Severity Index (PDSI) is used for the quantitative estimation of droughts on a monthly basis. Emphasis is placed on drought identification and estimation as well as the severity and areal extent of the phenomenon. The results indicate that there are several drought periods which are common to all stations in central and northern Greece, characterized by significant severity and time duration. There are also a large number of drought periods during the summer months as well as during the winter months.With 7 Figures  相似文献
