摘    要:根据 TOPEX/ POSEIDON-ERS高度计提供的海平面高度异常资料和并行海洋气候模式(POCM)模拟海平面高度资料,分析了南海海平面高度年循环特征。结果表明:l月,3月和5月海平面高度的异常值分别与7月,9月,11月的异常值相反。l月(7月),深水海区与吕宋海峡的海平面高度为负(正)异常,在大部分陆架区和南海的西和南部,海平面高度为正(负)异常。在3月(9月),除海平面高度异常的量级已减少,且较小的SSH正异常(负异常)出现在南海的中部以外,海平面高度异常的分布型与 1月(7月)类似; SSH的年循环的最大振幅出现在吕宋岛的西北海域;风的季节变化是南海SSH季节变化的主要原因。

关 键 词:海平面高度  南中国海  季风  并行海洋气候模式

Abstract:The annual cycle characteristics of the SSH in the South China Sea (SCS) are analyzed based on the Sea Surface Height (SSH) anomaly data from the TOPEX / POSEIDON-ERS altimeter data and the Parallel Ocean Climate Model (POCM) prediction. The results show that the distributions of the SSH anomalies of the SCS in January, March and May, are opposite to those in July, September and November respectively; In January (July) there is the SSH negative (positive) anomaly in the deep water basin and at the Luzon Strait, while there is positive (negative) anomaly on the most of continental shelves in the west and south of South China Sea; In March (September) the SSH anomalies are similar to those in January (July), although their magnitudes have decreased and a small positive (negative) anomaly appears in the center of the South China Sea; The amplitude of the SSH annual cycle reaches its maximum in the Northwest of the Luzon Island; The seasonal variability of the wind stress is dominant in the formation of the SSH seasonal variability.
Keywords:Sea Surface Height  South China Sea  Monsoon  Parallel Ocean Climate Model
