摘　　要：统计了44年来影响浙江海域的温带气旋及特征,并采用WRF中尺度数值模式对一次影响浙江海域的温带气旋的发生发展过程进行云迹风同化试验。通过分析时空变化特征和一次温带气旋发展过程中高低空的物理场变化,寻找温带气旋预报的着眼点。In this study,the characteristics of the extra tropical cyclones which influenced the Zhejiang coastal water in the past 44 years are discussed.The Weather Research and Forecasting （WRF） model system,which is typically used in the regional meso-scale model prediction,is used to simulate the process of extra tropical cyclones.During this process,the characteristics of temporal and spatial variation of extra tropical cyclones,and the atmospheric field variation at middle-high level are analyzed and examined.Meanwhile,the forecasting focus of this type of mid-latitude cyclones is discussed.
