An analysis is made statistically of the EastAsia monsoon intensity change regularities from 1951 to 2004, as well as the relation of EastAsian winter/summer monsoon intensity changes to winter temperature and summer precipitation in Hebei Province. The results indicate that during the stage of strong winter monsoon, the winter temperature of Hebei Province is somewhat lower than the normal, and vice versa. There is correlation between summer monsoon intensity and summer precipitation. In the years of strong summer monsoon, the summer precipitation tends to increase, and vice versa. The intensity of the summer monsoon has a relation with the arriving time of summer monsoon. When the summer monsoon comes early, the intensity of summer monsoon is strong, and vice versa.
