Research Abstract

The present study found by the data from the current satelliteand the global non-hydrostatic numerical model that the downward coupling process from stratosphere to troposphere in the Tropical Tropopause Layer (TTL) during the stratospheric sudden warming event (SSW) through analyzing the TTL parameters, such as vertical wind, diabatic heating, water vapor and ozone.
