  5. During El Nino, vertical propagation of Rossby wave and divergence of Eliassen-Palm flux will be enhanced, which will accelerate the Brewer-Dobson circulation (Garcia- Herrera et al., 2006). Thus the vertical flow in the tropical stratosphere will be accelerated. It will lead to a decrease in total column ozone in the tropical region and an increase of total column ozone in the middle to high latitudes.
