A possible mechanism of the Scandinavian ozone loss

摘要

Satellite data analysis shows an important Arctic ozone loss over the Scandinavia, with -50 DU in winter, equivalent to 15/100 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 a- long 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.
