Data from a number of sources are used to examine the climatology of the southern hemisphere middle atmosphere. The stratospheric data used are winds and higher order quantities derived from stratospheric analyses provided by the U.S. National Meterological Center and the British Meteorological Office. Mesospheric winds are used from a number of years of continuous partial reflection radar observations at four southern hemisphere sites. A comparison of the stratospheric analyses is used to highlight the regions of inadequacy in the data, and to assess its reliability. A three year zonal mean climatology of the stratosphere is provided, and compared on an individual monthly basis with a time mean mesospheric climatology. This comparison highlights the importance of interannual variability in both the stratosphere and mesosphere, and emphasizes the mesospheric dependance on the stratospheric state below. Wave motions are traced propagating through the stratosphere and tentatively identified in the mesospheric winds. One particular wave, the four day wave is examined in detail, and shown to exist on occasion in both the stratosphere and mesosphere. Some suggestions for further work are presented, with respect to both data comparisons and stratosphere-mesosphere interactions.
