The Microwave Limb Sounder observed waves in stratospheric temperature and O 3 during the 1992 southern winter. Wave 1 intensifies three times from mid August through mid September, when a 9 day eastward traveling wave becomes in phase with the stationary wave 1. During the periods of wave intensification, minor sudden warmings and increased zonal mean O 3 are observed. The waves have a westward phase tilt which results in an intensified baroclinic zone when the waves are in phase. Waves in T and O 3 are positively correlated near 5–10 hPa, implying transport by planetary waves; this is supported by larger O 3 wave amplitudes than expected from photochemistry alone.
