Simulation of Typhoon’s Anomalous Track (Ⅱ)——CD Method

摘要: 我们提出采用等值线动力学(CD)方法研究台风的运动。讨论了在不同的环境引导气流下,台风的非对称内部结构对台风异常路径的影响。为了证明该方法的可行性,我们以Yancy(9012)台风为例,模拟了台风从8月20日到22日的运动。数值计算结果表明,这一方法能定性地描述台风打转趋势。

Abstract: Contour dynamics (CD) method for the motions of typhoon is presented in this paper. The effect of asymmetric inner structure on the typhoon's anomalous track has been discussed in different environmental steering. To demonstrate the feasibility of the method, the track of Typhoon Yancy (9012) is concerned with. The numerical results show that the method can describe the tendency of looping qualitatively.
