| 摘 要： | 针对现今台风数值预报中强热带气旋切向风廓线设计上的困难，提出了一种利用台风报告中7级风和10级风的半径来确定台风切向风廓线的方法。它既可反映真实台风外围结构又避免了强风速切变问题。该方案有可能改进台风尤其是异常路径台风的预报效果，具有广阔的业务应用前景。

| Abstract: | A kind of tangential wind profile for strong tropical cyclone is constructed in this paper with the consideration of real 30 knots and 50 knots wind radius. This profile scheme can not only describe TC outer structure accurately, but also solve the strong wind shear problem. Numerical simulation of this paper shows that this scheme does have positive contribution to abnormal tropical cyclone track simulation and would have a broad prospect for operational practice. |
