摘要
统计分析了1951-2004年东亚季风强度历史变化规律以及东亚冬、夏季季风强度变化与河北省冬季气温和夏季降水的关系。分析表明:在冬季季风强盛阶段,河北省冬季气温以偏低为主;在冬季季风衰弱阶段,河北省冬季气温以偏高为主。夏季季风强度和河北省夏季降水呈正相关,夏季季风强的年份,河北省夏季降水偏多的几率较大,而夏季季风弱的年份,河北省夏季降水一般偏少。夏季季风的强弱与夏季季风来临迟早还存在着联系,夏季季风来临早的年份,则夏季季风强度以偏强为主;夏季季风来临迟的年份,夏季季风强度以偏弱为主。
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.
