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.
