Drought trends over part of Central Europe between 1961 and 2014

Original language description

An increase in drought frequency, duration and severity is expected for the CentralnEuropean region as a direct consequence of climate change. This will have profound effects on annumber of key sectors (e.g. agriculture, forestry, energy production and tourism) and also affectnwater resources, biodiversity and the landscape as a whole. However, global circulation modelsnsignificantly differ in their projections for Central Europe with respect to the magnitude and timingnof these changes. Therefore, analysis of changes in drought characteristics during the lastn54 yr in relation to prevailing climate trends might significantly enhance our understanding ofnpresent and future drought risks. This study is based on a set of drought indices, including thenStandardized Precipitation Index (SPI), the Palmer Drought Severity Index (PDSI), the Palmer Zindexn(Z-index) and the Standardized PrecipitationEvapotranspiration Index (SPEI), in their mostnadvanced formulations. The time series of the drought indices were calculated for 411 climatologicalnstations across Austria (excluding the Alps), the Czech Republic and Slovakia. Up to 45% ofnthe evaluated stations (depending on the index) became significantly drier during the 19612014nperiod except for areas in the west and north of the studied region. In addition to identifying thenregions with the most pronounced drying trends, a drying trend consistency across the station networknof 3 independent national weather services was shown. The main driver behind this developmentnwas an increase in the evaporative demand of the atmosphere, driven by higher temperaturesnand global radiation with limited changes in precipitation totals. The observed dryingntrends were most pronounced during the AprilSeptember period and in lower elevations. Conversely,nthe majority of stations above 1000 m exhibited a significant wetting trend for both thensummer and winter (OctoberMarch) half-years.
