Dynamical Perturbations to the Ozone Layer

MAR 01, 1990

Global‐scale disturbances in the stratosphere produce substantial changes in the abundance and distribution of ozone and prevent the formation over the North Pole of an ozone hole like that observed over Antarctica.

Several years ago spectrophotometer measurements revealed substantial depletions of atmospheric ozone over Antarctica, reviving concerns over damage to Earth’s ozone layer by human activities. These ground‐based observations were subsequently verified in global ozone data that had been collected by satellite for years. The sizable ozone depletions over Antarctica are now believed to arise from complex chlorine chemistry, stimulated ultimately by the emission of man‐made chlorofluorocarbons into the atmosphere.
