The GLOWA-Danube climate trends

Abstract

GLOWA-Danube, in order to simulate climate change impacts, needs meteorological drivers with high spatial and temporal resolution which reflect the temporal course of the regional climate change signal. Uncertainty in the amount and course of future climate change motivates to define and analyse the impact of a range for assumed temperature and precipitation changes. The GLOWA-Danube approach to define a range of climate change trends and their temporal courses is described. It combines results from global and regional climate models with a thorough analysis of observed climate data to define a realistic range of four climate trends and their different temporal courses until 2100. The results of the trend analysis are shown and discussed.
