【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.
[Abstract]:Based on the observed wave data at the Beihai offshore station in Guangxi for 1 year, the characteristics of the waves in this sea area are analyzed. The results show that the annual mean value of the sea area is 0.6 m, the normal wave direction is WSW direction, the frequency of occurrence is 15.48 and the strong wave direction is ESE direction. During the observation period, the maximum wave height appeared in the period of 201409 "Weimason" typhoon, the maximum value of Hmax was 8.23 m, corresponding to 1 / 10 of H _ S _ (1 / 10) was 6.26 m, and the joint distribution of wave height and period was similar to that of oblique triangle. The correlation between the characteristic wave height and the average wave height in the sea area was established by least square regression analysis.
