基于Holland参数化风场模型的浙江沿海台风浪数值模拟
Numerical simulation of typhoon-induced waves in Zhejiang coastal waters using the Holland parameterization model
摘要
Abstract
Parameterized wind field models are widely used in simulating typhoon-induced waves,with the accu-racy of such simulations heavily influenced by the parameterization schemes used for key wind field variables.This study aims to identify the optimal combination of Holland wind field parameters,namely the wind profile parameter B and the maximum wind speed radius parameter Rmax,suitable for typhoon wave simulations in Zhejiang coastal waters.Using the SWAN model,we conducted numerical simulations of ten typical typhoon wave events affecting the Zhejiang waters since 2011.Focusing on wind speed and significant wave height,we calibrated combinations of B and Rmax against observational data from meteorological stations and wave buoys during four typhoons;this cali-bration process led to the selection of an optimal parameter set for B and Rmax.Furthermore,we validated this pa-rameter combination by comparing significant wave height data from Jason satellite observations against simula-tions of wave spatial distribution during ten typhoon events.The results indicate that the Rmax parameter has a greater impact on the accuracy of wind speed and significant wave height simulations compared to the B parameter.Among the tested combinations,using Willoughby's expression for Rmax in conjunction with Powell's expression for B yielded the most accurate results.This combination successfully captured the temporal variations in wind speed and significant wave height while also reproducing the spatial distributions of typhoon-induced waves.Overall,the model achieved a correlation coefficient as high as 0.90 when compared with Jason satellite observations.关键词
