| 英文摘要: |
| The future climate dynamical downscaling method is that output of general circulation models (GCMs) is employed to provide initial conditions, lateral boundary conditions, sea surface temperatures, and initial land surface conditions to regional climate models (RCMs). There are two methods of downscaling: offline coupling and online coupling. The two kinds of coupling methods are described in detail by coupling the Weather Research and Forecasting model (WRF) with the Institute of Atmospheric Physics of Chinese Academy of Sciences Atmospheric General Circulation Model Version 4.0 (IAP AGCM4.0) in the study. And the extreme precipitation event over Beijing on July 21 2012 is simulated by using the two coupling methods. Results show that online coupling method is of great value in improving the model simulation. Furthermore, the data exchange frequency of online coupling has some effect on simulation result. |
