| Description: |
nbsp;This study analyses long-term changes in drought indices Standardised Precipitation Indexmdash;SPI, Standardised Precipitationndash;Evapotranspiration Indexmdash;SPEI at 1 and 3 months scales at 182 stations in 11 central and eastern European countries during 1949ndash;2018. For comparative purposes, the necessary atmospheric evaporative demand AED to obtain SPEI was calculated using two methods, Hargreaves-Samani SPEIH and Penman-Monteith SPEIP. The results show some relevant changes and tendencies in the drought indices. Statistically significant increase in SPI and SPEI during the cold season Novemberndash;March, reflecting precipitation increase, was found in the northern part of the study region, in Estonia, Latvia, Lithuania, northern Belarus and northern Poland. In the rest of study domain, a weak and mostly insignificant decrease prevailed in winter. Summer season Junendash;August is characterized by changes in the opposite sign. An increase was observed in the north, while a clear decrease in SPEI, reflecting a drying trend, was typical for the southern regions: the Czech Republic, Slovakia, Hungary, Romania, Moldova and southern Poland. A general drying tendency revealed also in April, which was statistically significant over a wide area in the Czech Republic and Poland. Increasing trends in SPI and SPEI for September and October were detected in Romania, Moldova and Hungary. The use of SPEI instead of SPI generally enhances drying trends.nbsp |
