Ozone Evolution Peculiarities in the Polar Regions: Analysis of Observational Data and Results of Modeling

Analysis of ozone evolution peculiarities in intra-annual evolution of latitude-altitude and latitude-longitude atmospheric ozone concentration fields was carried out using a special method of amplitude-phase characteristics. The TOMS satellite ozone data for the period 1978-1987 were used in the an...

Description
Summary:Analysis of ozone evolution peculiarities in intra-annual evolution of latitude-altitude and latitude-longitude atmospheric ozone concentration fields was carried out using a special method of amplitude-phase characteristics. The TOMS satellite ozone data for the period 1978-1987 were used in the analysis. Comparison was made with results of analysis of total ozone evolution based on data obtained from the World Data Center for Ozone (Toronto) and from the Main Geophysical Observatory (Leningrad) for the period 1973-1985 at 133 Northern and Southern hemisphere stations. Latitude-altitude peculiarities of the evolution of ozone concentrations from different satellite data are compared with results of simulations using a two-dimensional photochemical model of the atmosphere. There are large differences in ozone evolution in polar latitudes of the Northern and Southern hemispheres in different stratospheric layers and for different seasons. Particularly it was noted that the ozone hole phenomenon is more pronounced in the Antarctic than in the Arctic. Comparison with results of standard harmonic analysis was also carried out.
