摘要
基于POM三维海洋高分辨率数值模式,研究南海海面高度季节性变化和海面高度异常的季节性变化规律。研究结果表明,南海海面高度季节性变化显著,其中冬季和夏季海面高度分布规律相反,春季和秋季海面高度分布规律相反。冬季海面高度与南海海面高度年平均值相比,南海深水海盆和吕宋海峡位置处表现为海面高度负异常;而夏季,这两处位置则表现为海面高度正异常。春季和秋季海面高度异常分布特征整体表现为:春季在南海深水海盆中部表现为海面高度正异常,而秋季则表现为海面高度负异常。
In this paper,the seasonal variation of sea surface height and seasonal variation of sea surface height anomaly are studied based on the three-dimensional ocean high-resolution numerical POM model. The results show that the seasonal variation of sea surface height is significant,and the sea surface height distribution is contrast in winter and summer,and also in spring and autumn.Compared to the the annual average sea surface height,the sea surface height in winter is negative anomaly in eep water basin and the Luzon Strait position,summer is just the opposite of the winter.The sea surface height anomaly distribution of spring shows that positive anomaly in the center of deep water basin in the South China Sea,while the autumn showed the negative anomaly.
