汕头近岸区的台风波浪 (二)后报台风波浪及其基本特征

THE TYPHOON WAVE ON SHANTOU COASTAL AREAS

本文采用《受陆岸影响浅水区台风风浪的推算方案》后报影响汕头近岸区的台风风浪，并以此与Ｔｈｏｍｐｓｏｎ关于波型的判据和合田良实的不同波型能量集中度的规定相结合，计算台风混合浪，经与现场实测资料相比较，效果良好；依４４年台风浪的后报结果，可以得到各场台风过程的波高。

This article uses the method on “The calculation method for wind wave of tropical storm in shallow water areas under the influence of the coast” to hindcast the typhoon wind ware which affects shanton coastal areas.combining this process with the Thompson wave type criteria and the Yosim Goda′s formulation on energy concentration degree of different wave type,we calcnlate the typhoon mixed waves,comparing with the field observed data,and the calculated result is found good.Hindcasting 44 years typhoon wares,it gets the wave heights,wave energy and rariations of the main wave direction during each typhoon proceas and also hindcasts the variations of wave energy as direction at the moment of maximum wave height.
