摘要：

[1] In this study the possible change of the Indian summer monsoon associated with the anticipated increase in the greenhouse gases concentrations is investigated. This is done on the basis of a time-slice experiment performed with the ECHAM4 atmospheric GCM at a high horizontal resolution of T106. The first time-slice (1970-1999) represents the present-day climate and the second one (2060-2089) the future climate. The time-slice experiment predicts an intensification of the rainfall in the Indian region during the monsoon season due to the general warming, while the future changes in the large-scale flow indicate a weakening of the monsoon circulation. The increase of the regional rainfall is related to an intensification of the atmospheric moisture transport into the Indian region.
