The influence of lower stratospheric forcing on the October Antarctic ozone decrease

Abstract

A pattern correlation is found between the 30-mb zonal average ozone and temperature at 70 deg S during the October months and the 100-mb Eliassen-Palm (E-P) fluxes for the seven Septembers of 1979 to 1985, suggesting a dynamical influence on the long term trend of ozone and temperature values in the Southern Hemisphere for this period. For the August E-P fluxes and September values, this relationship is found to hold for temperature while not being strong for ozone. No explanation is found for the anomalously warm temperature values noted for both September and October 1982.
