"For the first time, sufficient loss occurred to reasonably be described as an Arctic ozone hole," write researchers in an article released online Sunday by the journal Nature. Some degree of ozone loss above the Arctic, and the formation of the Antarctic ozone hole, are annual events during the poles' respective winters. They are driven by a combination of cold temperatures and lingering ozone-depleting pollutants. The reactions that convert less reactive chemicals into ozone-destroying ones take place within what is known as the polar vortex, an atmospheric circulation pattern created by the rotation of Earth and by cold temperatures. This past winter and spring saw an unusually strong polar vortex and an unusually long cold period.
This year's record vortex persisted over the Arctic from December to the end of March, and the cold temperatures extended down to a remarkably low altitude, the researchers write. At altitudes of about 11 to 12 miles (18 to 20 kilometers), more than 80 percent of the ozone present in January had been chemically destroyed by late March. The same dynamics create the infamous ozone hole over Antarctica. But above the South Pole, ozone is essentially completely removed from the lower stratosphere ever year. Above the North Pole, however, ozone loss is highly variable and has, until now, been much more limited, according to an international research team led by Gloria Manney of the California Institute of Technology. Countries agreed to end their production of the substances ultimately responsible for destruction of the ozone in 1987 with the Montreal Protocol. However, these pollutants, including chlorofluorocarbons, still linger in the atmosphere.
