MLS OBSERVATIONS OF STRATOSPHERIC WAVES IN TEMPERATURE AND O3 DURING THE 1992 SOUTHERN WINTER

The Microwave Limb Sounder observed waves in stratospheric temperature and O3 during the 1992 southern winter. Wave 1 intensifies three time s from mid August through mid September, when a 9 day eastward traveli ng wave becomes in phase with the stationary wave 1. During the period s of wave intensification, minor sudden warmings and increased zonal m ean O3 are observed. The waves have a westward phase tilt which result s in an intensified baroclinic zone when the waves are in phase. Waves in T and O3 are. positively correlated near 5 - 10 hPa, implying tran sport by planetary waves; this is supported by larger O3 wave amplitud es than expected from photochemistry alone.
