摘要

现行台风模型大多采用基于有限实测数据修正的工程经验模型，忽略了波浪、海流等海洋运动与其水平风速之间的实时耦合作用。为揭示海洋运动对台风过境全过程的影响机制，基于MCT耦合器，采用中尺度WRF大气模型、第三代浅海海浪SWAN模型以及三维水动力FVCOM模型，建立了大气-海洋-海浪（W-S-F）的实时耦合模拟平台。在此基础上，模拟了台风“莫兰蒂”过境全过程海洋环境时空演变，对比分析了W-S-F耦合平台与非耦合WRF模式下台风过境全过程的差异性，最终提炼出海洋运动对水平风速特性的影响规律。结果表明：本文提出的W-S-F耦合平台可以准确模拟考虑海洋运动的台风过境全过程风速场；低空处海洋运动促进台风水平风速发展，且随高度增加影响逐渐减小，高空处海洋运动对台风水平风速产生抑制作用，且这种消耗随高度增大而加强；在台风整个发展周期，海洋运动对低空台风强度的影响呈现先促进后抑制规律，随着高度增加逐渐形成相反特点。

Abstract

Existing engineering empirical models for typhoon wind fields are corrected based on limited measured data and does not take the real-time coupling between the ocean movements (e.g. wave and ocean current) and the horizontal wind speed into account. To explore the influence of ocean movement on the whole typhoon landing process

an atmosphere-sea-wave (W-S-F) real-time coupling simulation platform was developed based on the MCT coupler by integrating the mesoscale WRF atmospheric model

the third generation of shallow sea wave SWAN model

and the three-dimensional hydrodynamic FVCOM model. On this basis

the spatial and temporal evolutions of marine environment throughout the whole landing process of typhoon “Meranti” were simulated. Next

differences between the W-S-F coupling platform and the decoupled WRF model throughout the typhoon landing process were analyzed regarding the pneumatic structure

vertical wind shear

heat flux

and friction velocity. Finally

effects of the ocean movement on horizontal wind speed characteristics and action mechanism were extracted. Results demonstrate that the proposed W-S-F coupling platform can simulate the wind field throughout the typhoon landing process with considerations of the ocean movement. At low-altitude spaces

ocean movement can promote typhoon horizontal wind speed

but this influence diminishes gradually with the increase of height. However

at high-altitude spaces

ocean movement inhibits the typhoon horizontal wind speed and such consumption is strengthened as a function of height.
