摘　　要：利用1953~2003年NCEP逐月再分析资料的海平面气压、500hPa高度场及850hPa风场的资料．计算了北太平洋涛动指数，利用小波分析得到，其呈现5～7年的周期变化，并分析了冬季北太平洋涛动指数与次年夏季海平面气压场、500hPa高度场、850hPa风场以及降水和温度的关系。Using monthly National Center for Environmental Prediction （NCEP） reanalysis data of Sea Level Pressures, 500hpa Geopotential Height and 850hpa Wind Fields for the period 1953~2003, this paper calculates the North Pacific Oscillation Index （Inpo） .From Wavelet Transform, the results show that there is an oscillation with a period of 5 or 7 years.Then,this paper discusses the relationship between Inpo during winter and Sea Level Pressures during summer the next year, 500hpa Geopotential Height, 850hpa Wind Fields, Rainfall, Temperature.

关 键 词：冬季北太平洋涛动 海平面气压场 高度场 温度场
