Title: Dynamical Influence on Inter-annual and Decadal Ozone Change

Statospheric Circulation is mainly driven by planetary waves. The transport of Ozone from its source region (tropics) to Polar region depends on this Brewer Dobson circulation. High wave activity leads to increase in Brewer Dobson circulation, weaker polar vortex and higher temperature. This wave activity is measured in terms of Eliassen-Palm Flux. Using ERA40 data set, inter-annual and decadal variability of this circulation will be presented.
