Wave-packet propagation feature of East Asia summer monsoon in 1998;

On the basis of analyzing the relationship between the setting of the East Asia summer monsoon over the South China Sea(the South China Sea monsoon) and the outbreak of harmful algal bloom over the East China Sea, the result of analyses shows that over three weeks after the South China Sea monsoon breaks out, the harmful algal bloom will occur over the East China Sea.

East Asia summer monsoon has a distinct interannual variability,and the external forcing is one of main causes resulting in the interannual difference of East Asia summer monsoon,but the effect of the tropical sea surface temperature is the most prominent.

Features of interdecadal changes of the East Asian summer monsoon and similarity and discrepancy in ERA-40 and NCEP/NCAR Reanalysis;

Recent progresses of studies on influence of ENSO on the East Asian summer monsoon and China summer rainfall;

Abrupt Character of the East Asian Summer Monsoon Recorded in the Annual Layer Thickness of Stalagmites During the Last Deglaciation;

A nonlinear projection of the East-Asian summer monsoon onto the summer precipitation over China was performed by applying a neural-network-based nonlinear canonical correlation analysis method(NLCCA).

,the South Asian summer monsoon(SASM) over area(0°-25°N,60°E-100°E) and the East Asian summer monsoon(EASM) over area(0°-45°N,100°E-140°E) in boreal summer,and the North Australian summer monsoon(NASM) over area(0°-15°S,110°E-150°E) in austral summer,are investigated by using the ERA-40 daily reanalysis data,the NCEP/NCAR daily reanalysis data and the Climate Predicti.

,the South Asian summer monsoon(SASM) over the area(0°-25°N,60°E-100°E) and the East Asian summer monsoon(EASM) over the area(0°-45°N,100°E-140°E) in boreal summer,and the North Australian summer monsoon(NASM) over the area(0°-15°S,110°E-150°E) in austral summer,are respectively investigated.

The interannual and interdecadal variations of the northerly wind system circulating around the west side of the Tibetan Plateau and their relation to the East Asian summer monsoon and the summer rainfall in North China are analyzed from the observed data.
