中文摘要: 应用逐月南极海冰北界资料和南半球海平面气压场资料,研究了南极海冰变异对华南后汛期旱涝的显著影响作用和可能机理,认为:南极总海冰、威德尔海海冰冰长期和罗斯海海冰最大面积的变异对后汛期的作用最为显著。9月罗斯海海冰最大面积变化与次年7~9月西太平洋副高关系密切,副高在海冰与后汛期关系中起重要纽带作用。后汛期旱涝可能是南极海冰变异产生的全球短期气候效应的结果之一

Abstract:By using the Antarctic sea ice data and solenoid fields data of sea level pressure over the southern hemisphere,the remarkable influence of Antarctic sea ice variance on dryness and wetness during late flood season in South China are studied. The results show that the acting of total Antarctic sea ice,Weddell sea ice in growing season and maximum area of Ross sea ice are the most remarkable. The area of Ross sea ice in September is closely related with the west Pacific high from July to September next year. Subtropical high is acting the mediums between Antarctic sea ice and dryness wetness during late flood season in South China. The variable of dryness wetness may be one of the results of global short range climatic effect caused by Antarctic sea ice anomalies.
