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