| 摘 要： | 本文系统的回顾了切断低压中典型多发系统,东北冷涡的定义、识别方法及气候特征的相关研究进展。东北冷涡识别方法包括主观识别、客观识别及主客观识别结合等。主观识别工作量大且可重复性低,客观识别是东北冷涡未来研究的重点。现阶段东北冷涡研究主要侧重于气候学研究,其定量化研究以物理形态及相关指数两个方面为主。东北冷涡概念化及定量化定义的完善,公开客观的数据集及相关行业标准的建立,内部机理研究及业务转换等方面有待加强。

| Abstract: | In this paper, the definition, identification and climatology of the Northeast Cold Vortex belonging to Cut off Lows were reviewed. The identification of Northeast Cold Vortex includes subjective analysis, objective (automated) analysis and hybrid objective-subjective analysis. However, the poor repeatability and the heavy workload are the main problems for subject analysis, so more attention would be received about the objective analysis. Climatology is the main focus of the Northeast Cold Vortex, and the main contents are the quantitative study of physical parameters and correlation indexes. The definition of the Northeast Cold Vortex is needed to improve, dataset and specifications should be set up, the mechanism of the Northeast Cold Vortex should be investigated and its application of the Northeast Cold Vortex should be improved. |
