Abstract This study examines the climatology and dynamics of atmospheric blocking, general circulation features that influence blocks in GFDL’s atmosphere-only (AM4) coupled atmosphere–ocean (CM4) comprehensive models. We compare AM4 CM4 with reanalysis, focusing on winter Northern Hemisphere. Both models generate correct blocking planetary-scale signatures stationary wave. However, at regional...

abstract in this paper, we modeled the climate of iran for future periods. each period is a 30-years period centered on a year. the range of periods is from 2000 (i.e., 1986-2015) to 2100 (i.e., 2086-2115). this was made using 2 general circulation models (echam4 and hadcm2) and 18 ipcc scenarios. magicc-scengen was used as a tool for downscaling gcm low resolution output data. result of hadcm2...

precipitation data is of utmost importance to carry out many hydro-meteorological studies. observed warming over several decades has been linked to changes in the large-scale hydrological cycle such as: increasing atmospheric water vapour content, changing precipitation patterns, intensity and extremes, reduced snow cover and widespread melting of ice, and changes in soil moisture and runoff. p...
