Abstract: | Satellite data analysis shows an important Arctic ozone loss over the Scandinavia, with - 50 DU in winter, equivalent to 15% of the total ozone over this region. The study shows a possible mechanism causing the ozone loss. The North Atlantic current carries the heat energy northwards, and causes a relatively high surface temperature along the Scandinavia. The high temperature over the east of North Atlantic heats the atmosphere, induces an upward mass lifting, and therefore causes an ozone divergence near 330°K isoentropic surface, which leads to a decline in the total ozone. |
