Ozone Distribution
				Antarctic Ozone Hole
	q The greatest production of ozone occurs in the tropics, where the solar UV flux is the highest. q However, the general circulation in the stratosphere transport ozone-rich air from the tropical upper stratosphere to mid-to-high latitudes. q Ozone column depths are highest during springtime at mid-to-high latitudes. q Ozone column depths are the lowest over the equator.
