考虑潮汐和潮流影响的台州湾台风浪数值模拟研究

Numerical simulation research of typhoon waves in Taizhou Bay considering the influences of tide and tidal current

为了模拟2018年14号台风“摩羯”过境台州湾时的波浪分布情况,利用Holland模式构造台风场,叠加CCMP(Cross Calibrated Multi-Platform)背景风场,由此驱动MIKE 21 SW波浪数学模型,同时也考虑了潮汐和潮流对波浪场的影响。验证结果表明:计算结果能够反映真实的波浪变化,也能够很好地反映台风对当地波浪产生的影响。受台风“摩羯”过境影响,台州湾内外波浪差异明显,整体表现为外大内小。

In order to simulate the wave distribution during the passing period of 1814 Typhoon"Yagi"in Taizhou Bay,the MIKE 21 SW wave mathematical model is driven by he typhoon field constructed from the Holland model and the Cross Calibrated Multi-Platform background wind field,and the influences of tide and tidal current on the wave field are also considered.The validation results show that the calculated results can reflect the real wave variation and the impact of typhoon on local waves.Waves inside and outside of Taizhou Bay were significantly different due to the passing of 1814 Typhoon"Yagi",and the overall performance was large outside and small inside.
