摘要
在原始方程中引人藤田气压模式、最大风速半径和风向内偏角等因子，经过合理的简化，推导出了适合计算海面热带气旋域内风速分布的公式。检验表明，该方法的计算结果与强、弱、西行或北上转向型的热带气旋的观测风场基本相符，对环境气压受副热带高压明显影响的热带气旋风场的计算效果尤好。
By using Fujita's pressure mode, radius of the largest wind speed and inner deflection angleof wind direction in the primitive equations, we have derived the formulas suitable for calculating distribution of wind speed of tropical cyclones over the sea. The experiment shows that the calculated resultsin accord with those of different types of observational tropical cyclones, strength and direction pattern.The results of wind field are pretty good for the simulation of tropical cyclones which are influenced bysubtropical high.
