Sudden stratospheric warning case study of January 2006 event

Abstract

Sudden stratospheric warming (SSW) refers to the event in which the polar stratospheric temperature rises by several tens of kelvin up to about 50k just in few days. The warmings vary in terms of its occurrence though on average is twice every two years. This event is characterized by rapid warming of the stratosphere, cooling of the polar air and this changes in the atmosphere and dynamics significantly affect the chemical composition of the middle atmosphere. I have analyzed the changes in the atmosphere,water vapor,GPH(Geophotential Height),hydroxyl and ozone in the stratosphere using temperature profile data from MLS Satellite instrument on board the Aura Satellite. I found out that, this event is the giant one ever on record as the temperature rises by 40_50kelvin just in few days and also lasted for about three months.
