北部湾海域风-浪-流耦合模式及其应用

Wind-Wave-Current Coupling Model and its Application in Beibu Gulf Waters

本文基于MCT耦合器,采用WRF、ROMS和SWAN模型,充分考虑海气相互作用和波流相互作用,建立了一个风-浪-流耦合数值模式,并利用该模式模拟计算了台风"启德"作用下北部湾海域的风浪过程和风暴潮过程,通过实测资料对耦合模式进行了验证,结果表明该模式具有较高的精度,能合理地描述风浪、潮汐风暴潮过程及其相互作用,可较好地应用于北部湾海域风暴潮及风浪的模拟和研究。

Based on MCT coupler,by using the WRF,ROMS and SWAN models,and fully considering the air-sea interaction and the wave-current interaction,this article established a wind-wave-current coupling numerical model,and used this model to simulate and calculate the wind wave process and storm surge process in Beibu Gulf waters under the influence of typhoon＂Kai-tak＂,and verified such coupling model through the measured data.The results showed that this model has high accuracy and can reasonably describe the storm wave,tidal storm surge processes and their interactions,which can be better applied to the simulation and research of storm surges and wind waves in Beibu Gulf waters.
