评估NOAA世纪和ERA-20 C再分析数据集在各自6个月冬季期间对北方和南半球的热带气旋和风暴的代表性。结果表明，两个数据集之间的低频变异性存在显著差异-特别是在世纪的上半叶-以不同的长期趋势符号和/或幅度表示。这阻碍了对气旋和风暴活动的真实的长期趋势进行可靠的分析。然而，两个数据集之间的高频变异性非常一致，尤其是对于北方。
NOAA 20th century and ERA‐20C reanalysis datasets are evaluated regarding the representation of extra‐tropical cyclones and windstorms over the Northern and Southern Hemisphere during the respective 6‐month winter seasons. The results indicate substantial differences in low‐frequency variability between the two datasets – especially in the first half of the 20th century – expressed in different signs and/or magnitudes of long‐term trends. This is hampering a reliable analysis of real long‐term trends of cyclone and windstorm activity. However, higher‐frequency variability is in good agreement between both datasets especially for the Northern Hemisphere.
