Dependence of ozone lamina characteristics on the distance from the polar vortex edge – possible relation to climate change
Ozone laminae are narrow layers of enhanced (positive) or depleted (negative) ozone concentration. Large laminae are formed at the vicinity of polar vortex and they are one of the mechanism of air masses exchange between the polar vortex and its surrounding. We observed similar long-term trend patte...

Ozone laminae are narrow layers of enhanced (positive) or depleted (negative) ozone concentration.
