摘要
In this paper,the complex land surface model BATSle was coupled to the PSU/NCAR MMSV3.And the coupled model was used to simulate the heavy rain in summers of 1991 and 1998.The results show that,with the detailed land surface parameterization,the model can (1) simulate the distribution of heavy rain in Yangtze River Basin in summers of 1991 and 1998 more precisely,and improve the results by increasing the simulated precipitation rate;(2)improve the simulation results of surface temperature:(3)improve the simulation results of the circulation and temperature fields at middle and high levels.
