摘要
采用海流和海浪数值模式,对热带气旋高风速作用下南海的海流和海浪进行了数值仿真。在海流仿真中采用了含波陡参数的风应力拖曳系数参数化方案和波浪辐射应力梯度作用,在海浪仿真过程中考虑了海流的作用。观测资料对数值仿真的结果验证表明,该数值模式对热带气旋高风速下的南海海流和海浪的数值仿真是可行的;海流的数值仿真与海面风拖曳系数参数化方案有关;考虑海流作用后,海浪的数值仿真更合理。
With the numerical sea current and wave model, the sea current and wave in the South China Sea under the actions of the tropical cyclone high wind speed were numerically simulated. In simulating the sea current, the parameterization scheme of the sea surface wind stress drag coefficient with wave deepness and the impact of the wave radiation stress gradient were both applied. In simulating the sea wave, the sea current impact was also considered. Comparisons between the simulation result and observed data show that it is feasible to simulate the sea current and wave forced by the strong wind of the tropical cyclone over the South China Sea with the numerical models. It also reveals that the sea current simulation has a close relationship with the parameterization scheme of the sea surface wind stress drag coefficient; moreover, the numerical simulation is more reasonable after considering the sea current impact.
