GLOWA Jordan River project provides applied scientific support for water managers in the Jordan River basin based on state-of-the art science, and explicitly addressing the problems associated with climate and global change in a transboundary context. Within GLOWA transient runs of the regional climate models MM5 and RegCM driven with boundary forcings from the ECHAM5 and HadCM3 general circulation models (GCM) are used to simulate the climate change signal for the Jordan River area. The main focus is set on the delineation of uncertainty ranges and the statistical analysis of extreme events as well as on provision of highly resolved meteorology data from the RCM runs as input data for subsequent impact analysis. In the dynamic downscaling approach the period 1960 to 2010 is considered: The spatial resolutions of the nested simulations are 54 km, 18 km and 6 km.
