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.
