| 摘 要： | 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一对数正态复合极值分布分析了该海区的重现期波高。

| Abstract: | The wavel climate (in terms of statistic concepts) is analyzed with three year wave data collected at Zhelang Ocean Observation Station.The results indicate that the two-parameter Weibull distribution fits the wave heights well, while the lognormal distribution fits the wave periods well.Wind wave is the dominant wave pattern in this sea waters and the higher waves are mainly produced by storms. The ratio coefficient of mean wave period to square root of mean wave height is 3.87.The autocorrelation coefficient of wave height with one-day lag is 0.42. The exponential curves fit the mean lasting time of calmless sea surface well. Finally,the extreme wave heights of this sea waters are analyzed based on the binomial-logarithmic-normal distribution. |
