A Study on the Variations of the Westerly Jet over East Asia and Its Relation with the Tropical Convective Heating
东亚西风急流变化与热带对流加热关系的研究

The annual cycle and interannual variation of the the westerly jet over East Asia and its relation with the tropical convective heating is studied by using the OLR data and gridded up-air data It is found that the annual cycle of the jet core is closely linked with the tropical convective heating The interannual variation of the westerly jet and the intensity of the subtropical westerly wind is closely related with the tropical convective heating It is also found the intensity of the subtropical westerly wind over East Asia in summer is closely correlated with the tropical convective heating in the previous months This relation can be used as a signal to predict the summer monsoon rainfall in the areas between the Changjiang and the Huaihe River basin
