摘要
摘要:台风双眼墙受到大尺度环境场强迫(如垂直风切变和高空槽/急流等)、海气相互作用和涡旋内部热动力过程共同作用，双眼墙的形成及其演变一直是台风研究中的热点和难点.虽然学术界提出了许多双眼墙形成和眼墙替换的可能机制，但一直未达成共识，尤其在平衡和非平衡、对称与非对称过程对双眼墙形成的相对贡献，以及边界层超梯度风的作用等方面还存在许多争议.本文重点梳理过去十余年来，国内外台风双眼墙统计特征、形成机制和演变机理等方面的发展现状及最新研究进展，讨论分析双眼墙研究中有待进一步解决的问题和发展方向，以期为下一步台风双眼墙研究提供有益的借鉴和参考.

Abstract:Concentric eyewalls of typhoon are forced by large-scale environmental fields (such as vertical wind shear and high-altitude troughs/jets, etc.), air-sea interactions, and thermal dynamic processes inside the vortices. The formation and evolution of concentric eyewalls have always been a hot and difficult topic in typhoon research. Although many researchers have proposed some potential mechanisms of typhoon secondary eyewall formation and eyewall replacement cycle, no consensus has been reached. Notable disagreements remain regarding the relative contribution of balanced and unbalanced, symmetric and asymmetric processes to the formation of secondary eyewall, and the effects of supergradient wind in the boundary layer. This article focuses on the development status and latest research progress of the statistical characteristics, formation and evolution mechanisms of typhoon secondary eyewall at home and abroad over the past ten years. Besides, the problems and development directions that need to be further resolved in the future are discussed and analyzed to provide useful reference for the development of typhoon secondary research.
