摘要
利用动力学方程组,并对其中垂直梯度项和垂直扩散项进行了参数化处理。利用每日4次的地面天气图资料和台风年鉴中台风中心位置资料,采用数值计算方法对热带气旋及其环境场进行数值计算模拟。计算结果表明,用本模式得到的热带气旋风场及其周围的环境风场比利用公式法得到的风场更为合理。
Dynamic equations are used in which the vertical gradient and vertical diffusion are parameterized.The data of pressure and wind from the ground weather chart of four times per day and the central position data of tropical cyclone are used. The wind fields of tropical cyclone and surrounding environment are computed by a numerical computation model.The computed results show that the wind fields of numerical computation are more rational than the wind fields of tropical cyclone formula.
