Intraseasonal Climate Characteristics of the Summertime Persistent Anomalous Circulation over Eurasian Middle and High Latitudes
夏季欧亚中高纬持续流型的季节内气候特征

By using synthesis,EOF analysis,numerical simulation and the other methods,this paper investigate the intraseasonal climate characteristics of two typical persistent flow patterns,pattern E (there are a longwave ridge,trough,ridge over the Ural Mountains,Lake Baikal,the Sea of Okhotsk,respectively) and pattern C (the positions of trough and ridge is opposite to pattern E's),over Eurasian middle and high latitudes in summer. The main conclusions are as follows:(1) The deviation of the actual frequency from t...
