摘要
通过风速和波浪的同步浮标观测数据,对3个台风过境期间台湾海峡内的台风浪动力机制和特征描述方法进行了分析研究。研究表明:台湾海峡内的台风浪具有明显的风浪成长特征,强烈的波波非线性相互作用引起的高低频能量交换是其主导机制。通过拟合方法给出了台风浪有效波高的模型关系,对台风浪灾害的预警报分析具有实际应用价值。
Buoy-based observations of surface winds and ocean waves during three typhoon events are used to study the dynamic mechanism and characteristics of typhoon waves in the Taiwan Strait.It is found that typhoon waves in the Taiwan Strait reveals significant characteristics of wind wave growth,and the high-low frequency energy exchange caused by strong nonlinear wave-wave interaction is the dominant mechanism.This paper proposes a model relationship of the significant wave height of typhoon waves using fitting method,which is of practical value to the early warning analysis of typhoon wave disaster.
