Voulgarakis, A., P. Hadjinicolaou, and J.A. Pyle, 2011: Increases in global tropospheric ozone following an El Niño event: Examining stratospheric ozone variability as a potential driver. Atmos. Sci. Lett., 12, 228-232, doi:10.1002/asl.318.

The stratosphere can strongly influence the interannual variability of tropospheric ozone. It has been discussed that tropospheric ozone can increase following an El Niño event, due to enhanced stratosphere/troposphere exchange (STE) of ozone. Here, we run a chemical-transport model for 5 years, including a strong El Niño event (1997-98), and find that stratospheric ozone variability is an almost negligible driver of modelled post-El Niño increases of ozone STE and tropospheric ozone abundances. Changes in the dynamics, which affect the cross tropopause air-mass flux, may be a far more important factor driving these anomalies.
