Abstract. This study gives an overview of interannual variations total ozone and 50 hPa temperature. It is based on newer longer records from the 1979 to 2001 Total Ozone Monitoring Spectrometer (TOMS) Solar Backscatter Ultraviolet (SBUV) instruments, US National Center for Environmental Prediction (NCEP) reanalyses. Multiple linear least squares regression used attribute various natural anthropogenic explanatory variables. Usually, maps temperature look very similar, reflecting a close coupling between two. As rule thumb, 10 Dobson Unit (DU) change in corresponds 1 K Large come trend term, up -30 DU or -1.5 K/decade, terms related polar vortex strength, 5 (typical, minimum maximum), tropospheric meteorology, 30 3 K, Quasi-Biennial Oscillation (QBO), 25 2.5 K. The 11-year solar cycle, El Niño/Southern (ENSO), are contributing smaller variations. Stratospheric aerosol after 1991 Pinatubo eruption lead warming at low latitudes depletion 40 high latitudes. Variations attributed QBO, lesser degree ENSO, exhibit inverse correlation higher cycle 400 temperature, however, have same sign over most globe. usually zonally symmetric mid-latitudes, but asymmetric There, position strength stratospheric anti-cyclones Aleutians south Australia appear vary with phases QBO ENSO.
