摘要
通过对广西北海近岸测站1 a实测波浪资料,分析该海域的波浪特征,得出:海域不分方向H_(1/10)年平均值为0.6 m,常浪向为WSW向,出现的频率为15.48%,强浪向为ESE向,观测期间最大波高出现在201409号"威马逊"台风期间,Hmax最大值为8.23 m,对应H_(1/10)值为6.26 m;波高与周期的联合分布基本呈类似斜三角形分布.运用最小二乘法进行回归分析,建立了该海域各特征波高与平均波高的相关关系.
Wave distribution characteristics of the southeast coastal area of Guangxi are discussed based on the analysis of one year＇s observed wave data from Guangxi Beihai offshore sea area.The results show that the annual average H1/10 is 0. 6 m regardless of direction, and the most frequently occurring direction is WSW with a corresponding frequency of 15.48%; during observation period, Hmax is 8. 23 m with a ESE direction and a corresponding H1/10 of 6. 26 m that was recorded during the typhoon 201409 Rammasun; the joint distribution of wave height and period of the area is similar to oblique triangle distribution.Using the least squares regression analysis method, we establish the correlation between each characteristic wave height and mean wave height of the research sea area.
