黑潮海域海洋异常加热与北半球大气环流的相互作用

根据黑潮海域海洋异常加热资料（１９５０－１９７９年），计算其与北半球大气环流相关，揭示二者相互作用事实，讨论其可能的物理过程，结果指出，黑潮海域海洋异常加热具有范围广，持续时间长，量级大等特点，在长期天气变化中占有重要的地位，冬半年海所相互作用为一正反馈过程，当亚洲大陆冷空气强时，海洋异常多加热，东亚大槽加深，后者又导致冷空气进一进加强；夏半年黑潮海域海洋异常加热主要受青藏高原热力状况制约。

AIR-SEA INTERACTION BETWEEN THE KUROSHIO REGION MARINE HEATING ANOMALY AND NORTHERN HEMISPHERE ATMOSPHERIC CIRCULATION

The characteristics of the Kuroshio region marine heating anomaly (based on 1950-1979 data) and its relation to atmospheric circulation were calculated and the physical process of the simu1taneous air-sea interaction in the middle latitude area are discussed. The results show that the Kuroshio region marine heating ano-maly extends over a large area, and is of long term persistence and huge magnitude, and therefore plays an important role in the long-range weather changes. In the winter half year, there is a positive feedback between the marine heating anomaly and the atmospheric circulation, i.e., the stronger the cold air over the Asia conti-nent, the larger the marine heating anomaly, tbe stronger the East Asia Trough,the stronger the cold air over Asia. In the summer ha1f year, the marine heating anomaly is controlled by the thermodynamical state of the Qinghai-Xizang Plateau.
