A possible mechanism of the Scandinavian ozone loss

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.     

斯堪的纳维亚臭氧亏损及其可能机制

卫星资料分析表明:北极地区的一个重要臭氧亏损区域位于斯堪的纳维亚(Scandinavia)上空,冬季臭氧总量亏损为50DU,相当于当地臭氧总量的15%.研究表明:冬季北大西洋暖流向北输送热量造成斯堪的纳维亚附近的高海温是该地区臭氧局地亏损的原因.冬季北大西洋东部的高海温对大气进行局地加热,使得整层物质抬升,进而在330K等熵面高度附近造成臭氧辐散,使得该区域整层大气臭氧总量减少.
