AN IMPROVED LAND-SURFACE PROCESSES MODEL AND ITS SIMULATION EXPERIMENT PART2:LAND-SURFACE PROCESSES MODEL (LPM-ZD) AND ITS COUPLED SIMULA-TION EXPERIMENT WITH REGIONAL CLIMATE MODEL

The Land-surface Process Model LPM-ZD has been successfully coupled with the regional climate model RegCM2 of NCA R.Then the new coupled model (CRegCM) has been applied to simulate the climate charact eristic of heavy rainfall in middle and east China for three months from May to July 1991,and compared with model output of NCAR-RegCM2 using BATS as land-surface process scheme,abbreviated NRegCM.The results show that CRegCM has good ability and performance.CRegCM successfully simulate the extreme precipitation event and the simulation of CRegCM for surface temperature and some physical variables related to land surface process are more reasonable than those of NRegCM.
