چکیده
1) Why did the authors consider a zonal mean climatology for their baseline? Why not use a spatial (lat-lon) climatology? Over the SH the stratosphere and the ozone layer have a distinct asymmetry determined by the presence of the quasi stationary wave 1. Furthermore, as noted in Malanca et al. (2005), this important aspect of mid to high latitude TOC has changed over time both in intensity and longitudinal location, affecting the baseline needed for the instrusion analysis. As these authors noted the evolution

Could stratospheric ozone depletion lead to enhanced aquatic primary production in the polar regions?
We study the effects of ozone depletion on primary production in ice-covered and open polar waters using a spectral radiative transfer model combined with a parameterization of the inhibition of marine photosynthesis by ultraviolet radiation. We find that ozone depletion might not have a negative influence on the aquatic algal community at high latitudes but instead could enhance primary produc...
متن کاملClimatological features of stratospheric streamers in the FUB-CMAM with increased horizontal resolution
The purpose of this study is to investigate horizontal transport processes in the winter stratosphere using data with a resolution relevant for chemistry and climate modeling. For this reason the Freie Universität Berlin Climate Middle Atmosphere Model (FUB-CMAM) with its model top at 83 km altitude, increased horizontal resolution T42 and the semi-Lagrangian transport scheme for advecting pass...
متن کاملLow ozone concentrations over Macquarie Island during 1997 Part I: trajectory analysis
Ozone concentrations have been decreasing globally for the last 20 years in part due to increasing chlorine concentrations in the stratosphere (WMO 1999). The most dramatic example of these reductions has been identified in the high latitude southern hemisphere, where ozone levels are nearly entirely depleted in the lower stratosphere during September and October each year. This phenomenon, whi...
