摘要
在实验室测得的大量风浪资料的基础上,经过谱分析和破波概率的计算,发现风浪破碎概率Pb与谱平衡域的频率指数P有指数关系:Pb∝exp(-3.88p)。当破碎概率2%~60%范围时,频率指数则在4.2~3.3变化。
Based on a large amount of wind wave data measured at the laboratory, the following relation between the wave breaking probability P b and the frequency exponent p in the spectral equilibrium range is derived from spectral analysis and the computing of wave breaking probability: the wave breaking probability P b changed from 2% to 60% while the frequency exponent p of the spectral equilibrium range changed from 4.2 to 3.3 during this course.
