摘　　要：针对热带气旋(tropical cyclone,TC)闪电已有研究,首先从闪电活动分布特征、眼壁闪电爆发对TC强度和路径的指示、外雨带闪电活动与雨带对流结构的关系三个方面进行了总结;其次从动力-微物理方面对TC闪电的形成原因和特征机理进行了梳理;最后提出当前研究中存在的两个关键问题,并对后续研究内容进行了展望。基于地基和空基相结合的综合闪电探测得到的闪电属性特征参量,有望建立一个明确的、具有代表性的闪电活动-TC强度变化关系。利用沿海地区架设的三维闪电定位系统结合地基双偏振雷达,针对登陆台风强对流过程开展的综合观测研究,将有助于推进闪电观测资料在台风中小尺度强对流监测、预警和资料同化中的应用。Based on previous studies on lightning activity in tropical cyclones(TC),this paper firstly summarizes the characteristics of TC lightning distribution,the indications of eyewall lightning outbreak on TC intensity and path,and the relationship between lightning activity and convective structure in the outer rainbands.Secondly,the formation and mechanism of TC lightning are summarized from the perspective of dynamics and microphysics.Finally,two key factors that affect the application of lightning data in TC monitoring and forecasting are discussed,and the future research contents are prospected.Using parameters of lightning characteristics(e.g.flash type,flash area,flash duration,flash radiation)obtained by both ground-based and space-based lightning detection systems,a more clear and representative relationship between lightning activity and TC intensity change will be established.The comprehensive observation study on the strong convection process of typhoon landing by using the three-dimensional lightning location system in coastal areas and the ground-based dual-polarization radar will be helpful to promote the application of lightning observation data in the monitoring,warning and data assimilation of meso-scale strong convective activity in typhoons.
