摘要:
在风的直接作用下产生的风浪,由于复杂的生成和发展条件,使其具有外观上的不规则性和随机性,内在的非线性性.早在五十年代初期,人们就针对风浪的随机性,运用统计方法,对风浪的统计性质进行了分析研究.就其外观而言,这种统计性质,主要由波面纵座标、波要素等的概率分布来描述,在把风浪作为一线性流体动力学模式来描述时,获得波面纵座标遵循正态分布律.
Abstract:
In the paper, a distribution function for wind wave heights is empirically prcsented.It involves, in addition to a shalowness factor, the parameteter describing the stage of wind wave growth. Some diagrams facilitating the, use of the distribution are also given. Comparison between the distribution proposed in the paper and some other existing ones are made by using field data.It is found that the distribution estabished here is in better agreement with the observations than Rayleigh and Glukovsky distributions.
