Abstract:
The paper discusses the relation between the seasonal transition from winter to summer indicated with evacuation of high from Indian area and general circulation in Northern Hemisphere and summer precipitation in China. It shows that during the early (late) year of seasonal transition from winter to summer negative (positive) anomaly of 500hPa height field in Indian area is dominant, West Pacific subtropic high is to the north (south), summer rainfall is plentiful (less). The anomaly disturbance of 500hPa height field in Indian area propogates as a wave along a passage through the extratropics in East Asia and polar to Western Hemisphere.
