Interannual and interdecadal variations of moisture transport by Asian summer monsoon and their association with droughts or floods in China;

Roles of tropical and subtropical land_sea distribution and the Qinghai-Xizang Plateau in the formation of the Asian summer monsoon;

The snow cover on the Tibetan Plateau has obvious seasonal,interannual and interdecadal changes,and is one of the most important factors which control the Asian summer monsoon precipitation.

High-resolution satellite data are used to analyze the features of the onset process of the tropical Asian summer monsoon(TASM) from the point of the climatology view.

The relationship between the location change of the East Asian subtropical westerly jet(EASWJ) and Asian summer monsoon onset is investigated by using NCEP/NCAR pentad mean reanalysis data.

By use of IAP9 AGCMⅡ, a numerical experiment is made, in which the influence of the south west Indian Ocean SSTA on the outbreak of the Asian summer monsoon has been discussed.

The spatial and temporal distribution features of onset period of mean rainy season over Asian monsoon region;

The variations of Asian monsoon as revealed by the variations of kinetic energy of barotropic/baroclinic modes of the wind field;

Thrusts and prospects on understanding and predicting Asian monsoon climate.;
