热带气旋结构和强度变化的物理过程和影响因子十分复杂，其登陆过程中海-陆-气三者之间的复杂作用常使其结构和强度发生突变，给热带气旋预报带来较大困难。近年，外场科学试验及数值模拟等科学方法均取得较大改进，在此基础上对热带气旋结构和强度研究取得了新的进展，如热带气旋强度突变及不同下垫面对热带气旋强度变化的影响等。但对热带气旋非对称结构对其强度的影响，及热带气旋内部结构变化与其强度之间的联系等问题的研究仍不全面。本文通过查阅国内外相关研究文献，从环境气流、下垫面及内部结构3个主要方面，总结影响热带气旋结构和强度变化的主要因子，以期为改进热带气旋结构和强度的预报方法提供理论依据。

Physical process of structure and intensity change of tropical cyclone (TC )and its influencing factors are very complex.Sea-land-atmosphere complex interactions in the landing process often lead to mutation of TC structure and intensity,which makes prediction difficult.Recent scientific methods such as field scientific experi-ments and numerical simulations have been improved.Studies on TC structure and intensity also have some new progresses,for example,abrupt intensity change of TC,and the impact of different underlying surfaces on changed TC intensity and so on.However,studies on some issues are still not comprehensive such as asymmetrical TC structure that impacts its intensity,and the relationship between TC interior structure and intensity.Based on a lot of literatures,this paper summarizes the main factors affecting TC structure and intensity including environmental air current,underlying surface and internal structure,which provides references for improving forecast methods of TC structure and intensity.
