Abstract. To improve the simulation of regional climate changes has been listed as one of the high priority areas in climatic change study, as it is the urgent requirement for usage in the impacts assessment. In the recent years, there are an increasing number of research groups developing or using different versions of RCM to simulate the regional climate in Asia. Some studies have demonstrated that the RCM can reproduce the seasonal evolution of monsoon rain-belts over Asia that very often is not captured by the GCM. However more systematic analysis of the RCM performance in Asia and inter-comparison study to evaluate the capacity of various RCMs in simulating the regional climate of Asia and RCM’s distinctiveness in comparison with the GCMs will be of great benefit for the further improvement of the RCMs for Asia.

This presentation introduces briefly a Regional Climate Model Inter–comparison Project (RMIP) for Asia under the join support of Asia-Pacific Network for Global Change Research (APN), Global Change System for Analysis, Research and Training (START) and Chinese Academy of Sciences(CAS) and several projects of other participating nations. The project is a join effort of 10 research groups from Australia, China, Japan, S. Korea and United States, but also involves scientists from India, Italy, Mongolia, North Korea and Russia.

The designed tasks include three phases to be implemented in four years since 2000: phase one, 18 months run from April 1997 to September 1998 which includes a full annual cycle and two extreme cases to assess the model performance in reproducing the annual cycle of monsoon climate and capturing the extreme climate events; phase two, 10 years run from January 1989 to December 1998 to assess the statistical behavior of the models and phase three to project the climate scenarios of the 21st century by nesting the RCM with the GCM.

The project design and some preliminary results of Phase one will be introduced in this presentation.
