Ozone Content over the Russian Federation in the Second Quarter of 2008

摘要

Total ozone (TO) over Russia is on average above the annual mean global TO of about 300 DU almost throughout the year. "Normal" dynamics of TO changes over Russia in the second quarter is shown in Fig. 1 Compared with the total ozone over Russia and adjoining areas in March, its content in April decreased. Total ozone continues to decrease in May and June, and the most significant decrease is observed in Eastern Siberia. The maximum TO decrease is observed in the region of the Sea of Okhotsk coast, while the minimum occurs in the south of European Russia. As a result, the TO distribution over Russia, which in the first quarter was largely meridional, becomes almost zonal by June. The "normal" TO of 320-340 DU should settle in June over Russia within the entire zonal belt of 45°-65° N; in lower and higher latitudes, the TO content should be somewhat lower.
