Marshall British Antarctic Survey, Cambridge, United Kingdom Michael Pook Institute of Antarctic and Southern Ocean Studies, University of Tasmania, Hobart, Australia Lance Cowled, Richard Jardine, and Stephen Pendlebury Bureau of Meteorology, Hobart, Australia Neil Adams Antarctic Cooperative Research Centre and Bureau of Meteorology, Hobart, Australia Abstract The quality of the Antarctic operational analyses that were distributed over the Global Telecommunications System during the First Regional Observing Study of the Troposphere project special observing period of July 1994 is considered. Numerical analyses from the U.K. Meteorological Office, the European Centre for Medium-Range Weather Forecasts, the Australian Bureau of Meteorology, and the U.S. National Centers for Environmental Prediction are compared with high quality analyses prepared using all available late data and high-resolution satellite imagery. The subjective assessment of the analyses indicated that no large, synoptic-scale systems were missing, but major discrepancies were found in terms of the depth of the lows, location errors, and failures to resolve the complexities of systems. Generally, the central pressures of the lows were handled better than the locations of the centers. Only 4 lows out of a total of 161 in the Eastern Hemisphere during the period 22–28 July had to be relocated more than 500 km. ...
