主　　题：Polar WRF precipitation Qinghai-Tibet Plateau downscaling simulations parameter optimization 

摘      要：Considering the complex topographic forcing and large cryosphere concentration,the present study utilized the polar-optimized WRF model(Polar WRF)to conduct downscaling simulations over the Qinghai-Tibet Plateau(TP)and its surrounding ***-group experiments with the 10 km horizontal resolution are used to evaluate the modeling of ***,on the basis of the model ground surface properties upgrade and the optimized Noah-MP,the“better-performingconfiguration suite for modeling precipitation is comprehensively *** model parameters such as nudging options,five cumulus parameterization schemes,two planetary boundary layer schemes,and six microphysics schemes are investigated to further refine the Polar WRF ***,the precipitation simulation for a full calendar year is compared with multiple reanalyses and *** simulations demonstrate that the Polar WRF model successfully captures the general features of precipitation over this region and is sensitive to model *** on the results,it is recommended to use grid nudging with q intensity coefficient of 0.0002,the multi-scale kain-fritsch cumulus parameterization,the Yonsei University boundary layer scheme,and the Morrison 2-mom microphysics with reduced default droplet concentration value of 100 ***,the model performance is better than the ERA-interim and TRMM *** is comparable to,and in some cases slightly better than,the CRA-Land,especially in the prediction for the western part of the plateau where in situ observations are limited,and the cryosphere-atmosphere interaction is more pronounced.
