摘要: 采用传统的理论模型或者经验公式构建台风动力场驱动海浪模式,无法反映台风影响下海气动力过程,难以为海浪模式提供高精度的台风风场、气压场数据。为解决这一问题,基于中尺度大气模式WRF和第三代海浪模式SWAN,构建大气-海浪实时双向耦合模式,并将其应用于理想台风的模拟之中。建立的WRF-SWAN耦合模式能够成功模拟理想台风影响下的台风浪分布特征,揭示了台风风场和台风浪在空间上的“右偏性”不对称分布特征,该模型可推广用于实际台风浪的模拟分析。

Abstract: In the previous studies, some traditional theoretical models and empirical models were used to construct the typhoon dynamic field, and the typhoon wind field and pressure field were used to drive the wave model. It could not reflect the sea-air dynamic process induced by typhoon and it was difficult to provide high-precision wind and pressure field data for the wave model. In order to solve this problem, a mesoscale meteorological model (WRF) and the third-generation wave model (SWAN) had been used to construct a two-way coupled atmosphere-wave model. This coupled model had been applied to the simulation of an idealized typhoon. The results show that the coupled WRF-SWAN model can successfully simulate the distribution of typhoon waves induced by an ideal typhoon and reveal the spatially asymmetric distribution called right side enhancement of typhoon wind field and waves field. This coupled atmosphere-wave model can be further promoted for simulation analysis of actual typhoon.

Key words: typhoon waves, numerical simulation, coupled atmosphere-wave model, real-time two-way coupled model
