The authors present the results of detailed studies of the northern and southern polar vortex development during 1991/1992, recreated from National Meteorological Center data. In general the data shows that in the southern hemisphere, the polar vortex developed with less short term variations, deepened very rapidly, and continued to grow well into the winter. Temperatures in the southern hemisphere would support the formation of polar stratospheric clouds for greater periods of time, and over larger areas than in the north. These results are compared to observations of ClO from the microwave limb sounder on the upper atmosphere research satellite. They lend support to the hemispherical differences observed in ClO by this probe, under the present model of reactive chlorine formation on polar stratospheric cloud particles.
