摘要
本文从波浪能量的角度提出了混合浪成分的概念,给出了混合浪能量成分的表达式和波高成分的表达式,在西北太平洋的深水大洋和近岸浅水海域上,使用GEO-SAT卫星高度计50个重复周期的观测资料,分别进行了海浪波高成分及其频率密度、频率密度累计率的计算。结果表明:在深水大洋波浪波高成分的概率密度统计曲线低而宽,混合波浪高H大于对应风速的充分成长波高H*的累计率为88%,最可能波高是对应风速的充分成长波高H*的1.5倍,最可能波高的概率密度为0.54;在近岸浅水域,概率密度曲线高而窄,小于对应风速的充分成长波高H*的累计概率为0.54,最可能波高是对应风速的充分成长波高H*的0.8倍,最可能波高的概率密度为0.87。
In the present paper, the definition of the Mixed Wave Energy Composition (MWEC) is given as ■ by wind wave energy and mixed wave energy,the formulations of MWEC, ■ are that of Mixed Wave Height Composition (MWHC), ■,are presented, statistical analysis is made on the MWHC for open ocean and marginal water in the north-western Pacific between 0°N ~45°N, 105°E^180°E with Geophysical Data Records from 50 repeated coverage of GEOSAT altimetric observational. The results manifest distinctive difference in the characteristics of MWHC for the open ocean and that for the rnarginal water
