CLIVAR AGCM Intercomparison Project


Welcome to the homepage of Asian-Australian Monsoon Atmospheric GCM Intercomparison Project.

 Asian-Australian monsoon (AA monsoon) plays a key role in affecting the livelihood of Asian and Australian region where more than 60% of the world population live. The agricultural, industrial, and economic productivities are heavily dependent on the variability of the monsoon in this region. In addition to this, there is strong linkage of the AA monsoon system to the global climate system, it can not be emphasized to much on its importance. Therefore better understanding and prediction of the AA monsoon are needed.

The atmospheric GCM(AGCM) have been widely used in predicting the monsoon. With all its progression and success, AGCM still has many predictability limitations. In a climate modeling sense, the intercomparisons between various AGCMs has a lot of advantages in improvement over the individual processes modifying a single model. It can help to pick up common problems, limitations and differences appearing in various AGCM models according to various treatments in their constructing a model, and understandings causing these will be very helpful to improve and individual model. So, the AGCM intercompany was proposed to promote the performance in AGCM and the monsoon predictability.

The AGCM intercomparison program was initiated right after the WCRP/CLIVAR Asian-Australian Monsoon Panel meeting held in Kyong-ju, Korea in April, 1998. The main foci of this program are intercomparing intraseasonal oscillation, monsoon dynamics and hydrology, atmosphere-ocean interaction, and global heat budget at the top of atmosphere and the surface in atmospheric GCMs. 14 GCM groups from 8 countries, that is CSIRO/Australia, IAP/China., IITM/India, MRI and CCSR in Japan, SNU/Korea, DNM/Russia, NCAR, GEOS(NASA), SUNA/GSFC(NASA), GFDL, COLA in U.S., UKMO/U.K. and NTU/Taiwan gave their interests in participating this program and are doing this monsoon intercomparison experiment with their models. In this page, we will give the outline of participating modeling groups, experimental design, Participaing Models, on-line model outputs, analysis results, news letters, and relevant other links.
