| 摘 要： | 回顾了中纬度海气相互作用的研究现状,分析了长期以来该项研究进展缓慢的原因和近十几年来的研究成果,结果指出:中纬度海洋在全球气候变化中有着重要的作用;冬季中纬度海气相互作用的强信号是冷空气强度;中纬度海洋强暖流区海气能量交换异常对同期和后期(半年至一年)北半球范围内的大气环流型有重要影响;当冬季黑潮和湾流海域海洋对大气同时异常多或异常少加热时,易形成夏季长江中下游偏旱或偏涝的环流形势。最后还提出,深入研究中纬度海气能量系统异常对大气环流影响及其物理机制,是今后海气相互作用研究的重要内容,其结果将为短期气候预测提供理论依据。

| Abstract: | In this paper, we reviewed the research condition of the mid latitude air sea interaction and examed the causes of slowly progressing and the main advances for recent 10 years on this project. The results indicated that, the mid latitude ocean plays very important role in world climate changes, the significant signal of mid latitude air sea interaction is the strength of cold air in winter time, and the marine heating anomaly over two strong warm currents region in the northwestern of the Pacific and Atlantic Oceans has important influence on the atmospheric circulation of Northern Hemmisphere both in simultaneous and following seasons (half to one year lag), very strong or very weak marine heating anomaly over Kuroshio and Gulf warm currents in winter may cause the drought or flood atmospheric circulation for the middle and lower reaches of Changjing river in summer. Finally, we proposed that, further exposing the influence of the mid latitude energy system anomaly on the atmospheric circulation and understanding the physical processes are the main objectives of the air sea interaction research, which will be very useful for the short term climate prediction. |
