Tropical cyclone (TC) Khanun in 2017 was simulated in this study by the Weather Research and Forecasting (WRF) model. The observation-validated simulation data were used to examine how asymmetric rotational and environmental flows played the roles in determining the contraction of the radius of maximum kinetic energy of symmetric rotational flow (Kψs). The radius of maximum Kψs was contracted rapidly before rapid intensification (RI) and moved inward slowly, then barely moved, and moved inward slowly again during RI.

热带气旋 Khanun 增强过程中最大对称旋转动能半径的收缩 （2017）


2017 年的热带气旋 （TC） Khanun 在本研究中由天气研究和预报 （WRF） 模型模拟。观测验证的模拟数据用于研究不对称旋转流和环境流如何在确定对称旋转流 （Kψs） 的最大动能半径收缩中发挥作用。最大 Kψs 半径在快速增强 （RI） 之前迅速收缩，然后缓慢向内移动，然后几乎不移动，在 RI 期间再次缓慢向内移动。
