Serial clustering of extratropical cyclones describes the passage of multiple cyclones over a fixed location within a given time period. Such periods often result in high precipitation totals and accumulated wind damage, leading to large societal and financial impacts. Here, we define the terminology to differentiate between several types of cyclone clustering and review multiple approaches used to quantify it. We provide an overview of current research activities including a review of serial cyclone clustering climatologies used to identify where clustering occurs. We review the dynamical mechanisms determining when and why serial cyclone clustering occurs for different timescales of interest. On daily timescales, serial cyclone clustering is often associated with a cyclone family and secondary cyclogenesis mechanisms. At longer timescales, active or inactive seasons are often associated with persistent large-scale flow patterns and their interaction with successive Rossby wave-breaking events. Finally, we discuss the knowledge gaps and current research opportunities.

温带气旋的系列聚类描述了多个气旋在给定时间段内在固定位置的通过。这样的时期通常会导致高降水总量和累积的风灾，从而导致巨大的社会和经济影响。在这里，我们定义术语以区分几种类型的旋风聚类，并回顾用于量化它的多种方法。我们提供了当前研究活动的概述，包括对用于确定发生簇群的连续气旋簇群气候的回顾。我们审查确定何时以及为什么在不同的时间尺度发生串行气旋聚类的动力学机制。在日常时间尺度上，串行旋风成簇通常与旋风家族和二级回旋机制有关。在更长的时间范围内，活跃或不活跃的季节通常与持续的大规模流型及其与连续的Rossby破波事件的相互作用有关。最后，我们讨论了知识差距和当前的研究机会。
