A possible mechanism of the Scandinavian ozone loss

Satellite data analysis shows an important Arctic ozone loss over the Scand inavia, with - 50 DU in winter, equivalent to 15% of the total ozone over t his region. The study shows a possible mechanism causing the ozone loss. Th e North Atlantic current carries the heat energy northwards, and causes a r elatively high surface temperature along the Scandinavia. The high temperat ure over the east of North Atlantic heats the atmosphere, induces an upward mass lifting, and therefore causes an ozone divergence near 330 degreesK i soentropic surface, which lends to a decline in the total ozone.
