Abstract

Radiative and dynamical impacts of Arctic and Antarctic ozone holes on the general circulation are investigated with the aid of a general circulation model developed at Kyushu University. The model includes a simplified ozone photochemistry interactively coupled with radiation and dynamics. Resultant temperature structure consisting of a cooling in the polar lower stratosphere and a warming in the polar upper stratosphere brings about the intensification of the polar night jet. The cooling is caused by the decrease of solar ultraviolet heating due to the ozone depletion, while the warming is caused by adiabatic heating due to the enhancement of downward motion.
