Dynamical control of NH and SH winter/spring total ozone from GOME observations in 1995-2002 / M. Weber, S. Dhomse, F. Wittrock, A. Richter, B.-M. Sinnhuber, J.P. Burrows.
Title: | Dynamical control of NH and SH winter/spring total ozone from GOME observations in 1995-2002 / M. Weber, S. Dhomse, F. Wittrock, A. Richter, B.-M. Sinnhuber, J.P. Burrows. |

Abstract: | Examines interannual variability in total ozone and chlorine activation as measured by Global Ozone Monitoring Experiment (GOME) combining data from northern (NH) and southern (SH) hemispheres. Abnormal high wave activity in austral spring 2002 led to first observation of major stratospheric warming in SH, resulting in net winter increase of mid- to high latitude total ozone until September 2002. In previous years chemical ozone depletion inside Antarctic vortex was sufficiently high to reduce mean total ozone south of 50° in September to values slightly below that of March as observed by GOME during period 1995-2001. Absolute winter eddy heat flux between 43° and 70° latitudes at 100 hPa correlates extremely well with spring-to-autumn ratio of total ozone polewards of 50° and anti-correlates with winter integrated maximum OClO column amounts using this combined data set. Unusual ozone ratio for austral winter/spring 2002 lies almost midway between typical values for Antarctica and those for recent cold Arctic winter/spring seasons. |
