Abstract The present work extensively describes the tropical dynamical changes during the Vortex split Major Stratospheric Warming (V-MSW) event occurred in recent decades. For better visualization of high latitude influence of tropical atmosphere, in this study, we have utilized three successive major vortex split warming events occurred in winters 1984/85, 1988/89 and 2008/09. The realistic visualization of planetary wave activity and its tropical response can be achieved by using Eliassen –Palm flux as a diagnostic tool. The investigation reveals that the tropical weather shows significant changes in temperature, convection and wind circulation during the course of vortex split major stratospheric warming.

对涡旋分裂突然平流层变暖的低纬度动力响应：Eliassen Palm 视角

摘要 目前的工作广泛描述了近几十年来发生的涡旋分裂主要平流层变暖（V-MSW）事件期间的热带动力变化。为了更好地可视化热带大气的高纬度影响，在本研究中，我们利用了 1984/85、1988/89 和 2008/09 冬季发生的三个连续的主要涡旋分裂变暖事件。通过使用 Eliassen –Palm 通量作为诊断工具，可以实现行星波活动及其热带响应的逼真可视化。调查显示，在涡分裂主要平流层变暖过程中，热带天气显示出显着的温度、对流和风环流变化。
