摘要几个气象数据集，包括英国，气象局、欧洲中期天气预报中心、国家环境预报中心和美国航天局的戈达德地球观测系统的分析正在用于对2002年南半球平流层冬季和南极主要变暖的研究。诊断进行比较，以评估这些研究可能会受到所使用的气象数据的影响。虽然整体结构和演变的温度，风，和波诊断在不同的分析提供了一致的图片的大规模动态的SH 2002年冬季，几个显着的差异可能会影响详细的研究。不建议将NCEP-NCAR再分析（REAN）和NCEP-能源部（DOE）再分析-2（REAN-2）数据集用于详细研究，特别是与极地处理相关的研究，因为平流层温度较低的偏差会导致低估极地处理潜力。
Abstract Several meteorological datasets, including U.K. Met Office (MetO), European Centre for Medium-Range Weather Forecasts (ECMWF), National Centers for Environmental Prediction (NCEP), and NASA’s Goddard Earth Observation System (GEOS-4) analyses, are being used in studies of the 2002 Southern Hemisphere (SH) stratospheric winter and Antarctic major warming. Diagnostics are compared to assess how these studies may be affected by the meteorological data used. While the overall structure and evolution of temperatures, winds, and wave diagnostics in the different analyses provide a consistent picture of the large-scale dynamics of the SH 2002 winter, several significant differences may affect detailed studies. The NCEP–NCAR reanalysis (REAN) and NCEP–Department of Energy (DOE) reanalysis-2 (REAN-2) datasets are not recommended for detailed studies, especially those related to polar processing, because of lower-stratospheric temperature biases that result in underestimates of polar processing potential, ...
