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.;

Diurnal cycle of marine atmospheric boundary layer during the 1998 summer monsoon onset over South China Sea

By using the 1950-1999 NCEP daily averaged reanalyzed data and based on the major atmosphere characteristics at 850 hPa during southwest monsoon onset in the South China Sea (SCS), it is suggested an objective atmospheric circulation way to define the onset dates of SCS southwest monsoon.

Based on the NCEP/NCAR reanalysis datasets,the influence of anomalous diabatic heating over the Tibetan Plateau(TP) in spring on the Asian tropical monsoon onset were investigated by performing composite analysis.

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.
