摘　　要：研究了我国月平均气温场的遥相关结构。指出,我国冬季月份的气温场的跷跷板特征不明显。夏季月份有明显的遥相关结构。给出了各月的遥相关模态及强度。指出,月平均气温遥相关表现为从南向东北、西北方向的辐射状。在105°E以东呈东北—西南向。在105°E以西呈西北—东南向。这种遥相关结构是由环流异常造成的,而且可以在区域的月平均气温场预报中使用。The teleconnection structure of the monthly mean temperature fields in China has been studied in this paper. Results show that the seesaw features of monthly mean temperature fields during winter months is not distinct While there is an obvious teleeonneetion structure during summer months. The monthly teleconneetion models and intensities are presented. It is pointed out that the teleconnections of monthly mean temperature appear in a radial pattern (from south to northeast and northwest,to the east of 105°E,northeast-southwest;to the west of 105°E,northwest-southeast. ) These structures are caused by the anomalous circulation and can be used in the forecasting of monthly mean temperature in large areas.
