  1. Response of total ozone to ENSO in the tropics Jiangfeng Wei

  2. ENSO (El Niño-Southern Oscillation)

  3. Southern Oscillation Index (SOI) El Niño SOI < 0 H L Pacific Darwin Tahiti La Niña SOI > 0 L H Pacific Darwin Tahiti

  4. Ozone Variation Oz=S+Q+SO+SA+TR+RE S seasonal Q quasi-biennial oscillation (QBO) SO ENSO SA solar activity TR linear trend RE residual component (Zerefos et al., 2001). Other factors, such as volcanic eruptions, anthropogenic emissions.

  5. Ozone Data World Ozone Data Centre (WODC) of World Meteorological Organization (WMO) (http://www.woudc.org/)

  6. Total Ozone Stations Singapore Darwin

  7. Ozone Loss Mechanism

  8. Vertical profile of the correlation between SOI and ozone concentration in Singapore over 1996-1999 (from Yonemura et al. 2002).

  9. Conclusion • ENSO plays an important role in tropical ozone variation. It affects ozone amount by changing the convection and moisture transport into upper level. • Ozone amount is also greatly affected by solar activity, QBO etc. They combined to decide the total ozone amount.
