摘要: Abstract Tibetan Plateau (TP, with the height > 3000 m) is a region complex topographical features and large diversity of climate both in space time. The use higher resolution regional models (RCMs) to downscale global model simulations high importance. In present study, future change over TP surrounding areas investigated based on ensemble set 21st century projections using RCM RegCM4. driven by five different GCMs at grid spacing 25 km under RCP4.5. focus December‒January‒February (DJF), June‒July‒August (JJA), annual mean temperature precipitation, comparisons against driving also provided. Overall, RegCM4 greatly improves simulation providing finer scale spatial details precipitation distributions region. topographic effects are well reproduced but not GCMs. For projected changes, general warming increase found GCM simulations. However, substantial differences exist distribution magnitude changes. added value for temperature, addition details, characterized more pronounced DJF compared its areas. changes show between basins RegCM4, better agreement across
