| 摘 要： | 通过对广东阳西近岸测站1a实测波浪资料及岸边同期风资料的整理与分析,探讨了该海域的波浪特性,得出研究海域不分方向H1/10年平均值为1.00 m,常浪向为SE向,出现的频率为38.35%,强浪向为SE向,观测期间的最大波高出现在0814号"黑格比"台风期间,Hmax值为8.31 m.用已有的理论分布函数对实测统计数据进行拟合,筛选出研究海域的波高分布、周期分布及波高与周期联合分布的特征,结果表明双参数威布尔理论波高分布、杨正己威布尔周期分布、朗格-赫金斯83模式或者孙孚模式较为适用于本海区的波高分布、周期分布、波高周期联合分布;结合相应的风速风向资料,运用回归分析方法,建立了该地区的波高与风速之间、波高与波周期之间的关系.

| Abstract: | Wave distribution characteristics of the western coastal area of Guangdong were discussed based on the analysis of one year’s measured wave and wind data from 10 m isobath of Guangdong Yangxi offshore.The results show that the annual average H1/10 is 1.00 m without regard to direction,and the most frequently occurring direction is SE with a corresponding frequency of 38.35%;during the observation period,Hmax is 8.31m with a SE direction as registered（recorded） during the typhoon 0814 ＂HAGUPIT＂.Using the theoretical distribution function to fit the measured statistical data,we get wave height,period and the joint distribution of wave height and period of the area.The results show that the two-parameter Weibull distribution is more suitable for wave height distribution in this region;when the spectral width is large,Yang Zhengji Weibull period distribution is more in line with the observed distribution;some differences exsists between measured wave height and period joint probability distribution with theory joint distribution.Combining with the corresponding measured wind data,regression analysis were used to establish the relationship between wave height and wind speed,and the relationship between wave height and wave period of the studied area. |
