主 题：CMIP6 HighResMIP Model evaluation Precipitation Elevation Central Asia
摘 要：The High Resolutio n Model Intercomparison Project(HighResMIP)experiment within the Coupled Model In tercomparison Project Phase 6(CMIP6),for the first time,has provided an opportunity to evaluate the performance of climate models over complex *** on the HighResMIP s historical simulations of atmospheric general circulation models,the performances of global high-resolution models,with a horizontal resolution finer than 50 km,in representing precipitation over Central Asia were evaluated using rain gauge observation *** the models successfully reproduce the large precipitation regions that are located over the mountainous areas and Northern Central ***,nearly all the models overestimate precipitation frequency over Central Asia and large overestimations of precipitation amount and frequency are located over the mountainous *** the HighResMIP multi-model ensemble mean performs better than all individual models at simulating the spatial pattern of precipitation frequency,it is inferior to HadGEM3-GC31-HM and ECMWF-IFS-HR at simulating that of precipitation *** simulation performance exhibits remarkable regional *** the Qilian Mountains,the relationship between precipitation and elevation is totally captured by climate *** contrast,over the Tianshan Mountains,the models fail to simulate the decrease in precipitation frequency after elevation higher than the maximum precipitation *** models successfully reproduce the annual cycle shape of precipitation amount over the Southern Central Asia,Qilian Mountains and Tianshan Mountains,but fail to reproduce it over the Northern Central *** than half of the high-resolution GCMs have a reduced bias relative to the corresponding low-resolution *** performances of most high-resolution GCMs in simulating precipitation pattern are well over the Tianshan Mountains.
