Projected Future Changes in Extreme Climate Indices over Central Asia Using RegCM4.3.5

This work projected future extreme climate indices’ changes over Central Asia (The Coordinated Regional Climate Downscaling Experiment—CORDEX Region 8). Changes were calculated for 2071–2100 relative to 1971–2000. simulations obtained by downscaling the RegCM4.3.5 50 km resolution under RCP4.5 and 8.5 with HadGEM2-ES MPI-ESM-MR. The results indicate that Asian domain will experience warmer more temperatures increasing radiative forcing. annual lowest value of minimum daily temperature was simulated increase remarkably, up 8 degrees, especially in high latitudes, a than 12 degree Siberia. A strong growth percentage warm nights an days spells whole region, decrease cold spell duration, are anticipated. Model show expected reduction 30% precipitation totals domain, except increased Siberia, Himalayas, Tibetan Plateau. Extreme events have 20% 80% topographical areas.
