| 摘 要： | 利用1992年12月-2005年3月TOPEX卫星高度计资料,对中国近海波浪季节特征及其时间变化进行了分析。分析结果表明,冬季平均波高最大,台湾海峡、南海北部、中南半岛东南海域以及吕宋海峡外侧是冬季的大浪区;夏季平均波高最小;春、秋两季为过渡期。对冬季大浪所在区域波浪时间变化的研究表明,年变化是其主要时间变化特征,而季节内变化是该海区的另一重要特征,并且以5 a为周期的年际变化与ENSO事件有着很好的对应关系。

| Abstract: | In this paper,the TOPEX satellite altimeter data observed from December 1992 to March 2005 are used to analyze the seasonal characteristics and temporal variations of ocean wave in the Chinese offshore waters.It is shown from the analysis results that the average wave height in winter is the greatest,and the high wave areas in winter are located in the Taiwan Strait,the northern South China Sea,the sea area southeast of Indo-China Peninsula and the sea area outside of the Luzon Strait;the average wave height in summer is the smallest;and spring and autumn are transitional seasons.It is shown from the study results that the annual variation of ocean wave in the high wave area in winter is the main temporal variation characteristics,the intraseasonal variation is another important feature,and the interannual variations of average wave height with a 5 year period are well consistent with the ENSO event. |
