Abstract:
The 30 global climate models from Coupled Model Intercomparison Project Phase 6 (CMIP6) have been evaluated in reproducing the climatological spatial distribution and major modes of midsummer precipitation over the monsoon region in the northern part of China (NCMR) during 1961–2014. Based on evaluation indexes, such as spatial correlation coefficient, root-mean-square error, interannual variability score, and relative deviation, it is concluded that four models (MPI-ESM-1-2-HAM, MPI-ESM1-2-HR, MPI-ESM1-2-LR, and E3SM-1-0) can well capture the spatial distributions of midsummer precipitation over the NCMR. Models that can comprehensively evaluate the climatological spatial distribution, EOF1 (EOF2), and its interannual variability of midsummer precipitation over the NCMR are NESM3, E3SM-1-0, GFDL-ESM4, and MMI-ESM1-2-LR (EC-Earth3-Veg, EC-Earth3, E3SM-1-0, NESM3, and MPI-ESM1-2-HR). The average simulation capability of a multimodel ensemble is better than that of most models.
