| 摘 要： | 针对冬、春季南海区风场，表层海流、海温场的季节变化，选用了２＾１／３层海洋模式和简单一层大气边界层模式，研究了冬、春季我作用下南海上层海洋环流的基本形态及其对ＳＳＴ的影响，估算了这种影响对海南风场的反馈效应。研究结果表明，冬、春季东北 与南海五流的相互作用对吕宋岛西部海域的气旋式冷涡的形成和维持有利。冬季（１月）强东北风作用使南海上层为一气旋式环流，上层环流对季风的反馈作用可使南海西北部东北风减弱

| Abstract: | The air-sea interaction of time scale larger than month is an importantmechanism of low frequency anomaly in the upper layer ocean and atmosphere. A 21/2-layer ocean model and a simple one-layer medel of the boundary layer in atmosphereare used in this paper to simulate the seasonal variation of the sea surface wind,surface current and SST in the South China Sea (SCS). The basic Pattern of the SCS'Supper layer ocean circulation foreed by the northeast monsson and its effect on the SSTare studied. Furthermore, feedback of SST on sea surface wind are calculated.The results show that the interachon between the northeast monsoon and SCScirculation favors the formahon and maintenance of the cyclonic cool eddy west ofLuzon Island during winter and spring. In winter (January), there is a cycloniccirculation forced by the strong northeast monsoon in the upper ocean. The feedbackeffect of the cyclonic circulation on the monsoon could make the northeasterly getweaker in the northWest and a little stronger in the southeast of the SCS, and make thecross-equatorial flow (from north to south) get stronger. In spring (April), the northeastmonsoon is weaker, a cyclonic circulation occurs in the south and the north, and ananticyclonic circulahon occurs between them. The feedback of the upper layer oceancirculahon on the monsoon could make the northeasterly get weaker in the SCS, andfavors changing of the cross-equatorial flow and formatting of the stimmer monsoon. |
