Correlation between stratospheric temperature, total ozone, and tropospheric weather systems
- Freie Universitaet, Berlin (Germany)
This paper discusses observations made during a situation in January, when there was an unusual ozone behaviour. At the edge of the polar vortex, there was a region of the middle stratosphere with quite cold temperatures, which was located over a warm anticyclonic block in the troposphere. The intervening tropopause layer was quite low in temperature also. In this situation there was a strong positive correlation between ozone partial pressures and ambient temperatures. This situation favors vertical mixing which can drive a decrease in ozone concentration, but it also favors the conditions which support chemical processes involving nitric acid trihydrate aerosols which can mediate ozone destruction reactions. Similar climatic situations have been observed in TOMS data in eleven cases over fourteen years.
