Because of polar temperatures, conditions in the Arctic vortex are favorable for formation of stratospheric clouds and subsequent lower stratospheric chlorine activation] and ozone depletion for a much shorter time than in the hemisphere [e.g., and 1993]. In addition, the more active and distorted hemisphere vortex makes it considerably more difficult to separate dynamical chemical [1 994a] ozone from the Microwave Sounder and nitrous oxide from the Cryogen Limb Array on the Atmosphere Research Satellite to show for chemical ozone in the Arctic during February and early March 1993.
