A new perspective on the dynamical link between the stratosphere and troposphere
Article Abstract:
It has been established that stratospheric processes lead to substantial anomalies in dynamical fields at the tropopause. If the wintertime Arctic polar stratospheric vortex is distorted, there is a corresponding redistribution of stratospheric potential vorticity which brings about perturbations in important meteorological fields in the upper troposphere. It appears that a more realistic representation of the stratosphere may be needed to allow general circulation models to fully simulate the troposphere.

Possibility of an Arctic ozone hole in a doubled-CO2 climate
Article Abstract:
A doubling of the carbon dioxide (CO2) concentrations in the atmosphere will cool the lower stratosphere causing the formation of polar stratospheric clouds (PSCs). Once formed, PSCs will activate compounds present that will cause the ozone depletion already observed over the Antarctic. A mathematical model of the Northern Hemisphere winter stratosphere shows formation of the hole and near total depletion of ozone at lower altitudes at doubled CO2 levels.

Removal of chlorofluorocarbons by increased mass exchange between the stratosphere and troposphere in a changing climate
Article Abstract:
Research is presented concerning the use of a global climate model to predict that the rate of mass exchange between the troposphere and the stratosphere will rise by 3% every 10-years in the 21st Century.
