作为观测系统研究和可预报性实验（THORPEX）交互式全球大集合（TIGGE）的一部分，最近利用气旋跟踪方法探索了9个不同集合预报系统（EPS）对北方半球（NH）温带气旋的预报。本文提供了这项工作的延续，扩展到南半球（SH）的分析。虽然EPS在南半球的所有气旋性质中具有较大的误差，但不同EPS的相对性能在两个半球之间保持大致一致。一些有趣的差异也显示。中国气象局（CMA）的每股收益显著低于
The prediction of Northern Hemisphere (NH) extratropical cyclones by nine different ensemble prediction systems (EPSs), archived as part of The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble (TIGGE), has recently been explored using a cyclonetracking approach. This paper provides a continuation of this work, extending the analysis to the Southern Hemisphere (SH). While the EPSs have larger error in all cyclone properties in the SH, the relative performance of the different EPSs remains broadly consistent between the two hemispheres. Some interesting differencesare also shown. TheChineseMeteorological Administration (CMA)EPS has asignificantlylower
