Аннотация:Physical-statistical approach is used for working out spatially detailed prognostic fields of air temperature and precipitation in the middle of 21 century in the Eastern Siberia. Initial data are monthly mean values averaged for ensemble of 12 global circulation models of atmosphere and ocean with spatial resolution 2x2 longitude and latitude degrees. They are downscaled on the 12,5x12,5 km grid considering geometric and reflective features of the surface. The most pronounce effect of downscaling is exhibited in regions with complex relief, especially in summer time. It follows from physically grounded pattern of processes influencing on the local features of precipitation and temperature fields, and confirm the efficiency of proposed method.
