利用遮浪海洋站3a的观测记录,对红海湾海域的波侯进行了分析。结果表明该海区的观测资料前后有差异。海区的波高比较符合两参数的Weibull分布,波浪周期符合对数—正态分布。该海区的波浪类型以风浪为主,其中大浪主要是由风暴引起。平均波周期和平均波高的方根的比例系数为3 87。波高1天滞后的自相关系数为0 42,不平静海面的平均延时符合指数形式。最后用日极值波高数据和二项—对数正态复合极值分布分析了该海区的重现期波高。
Based on the observation records of the shelter oceanographic station 3a, the wave-HO of the Red Bay waters was analyzed. The results show that there are differences in the observation data before and after the sea area. The wave height in the sea area is more in line with the Weibull distribution of two parameters, and the wave period is in log-normal distribution. The types of waves in the sea area are mainly storm waves, of which the main waves are mainly caused by storms. The ratio coefficient of square roots with average wave period and average wave height is 3 87. The autocorrelation coefficient of 1 day lag of wave height is 0 42, and the average delay of the sea surface is in exponential form. Finally, the daily wave height and the binomial-lognormal composite extreme value distribution were used to analyze the wave height of the return period in the sea area.
