摘要
Based on the correlation of 500hPa altitude field,teleconnection patterns in the Northern Hemisphere are investigated with their respective intensity indices calculated from 1956 to 2000.Then the relationship between each teleconnection pattern and the recipitation Guangdong Province,especially in Zhongshan is described.It is found that its relationship with the North-Pacific teleconnection in April and the North and West Atlantic Teleconnection in June are close.In addition,the West Atlantic teleconnection in June can be used to predict the rainfall next year in Guangdong.
