自20世纪90年代后期以来,热带气旋强度变化研究越来越受到人们的重视,随着研究的不断深入,热带气旋强度变化研究取得了可喜的进展,文中总结近年来热带气旋强度变化的主要研究成果,主要包括(1)热带气旋的发生、发展和最大可能强度的研究;(2)行星涡度梯度、环境均匀流、环境流场垂直切变以及热带气旋外流与环境流的相互作用对热带气旋强度的影响及物理机制;(3)热带气旋结构与强度的变化关系,着重总结环境流场导致的非对称结构变化而引起的热带气旋强度变化以及对涡旋倾斜发展理论验证,分析了涡旋Rossby波的最新研究;(4)海洋热状况变化以及海洋飞沫对热带气旋强度的影响研究成果。分析指出,今后进一步开展用现代化卫星探测资料研究热带气旋强度变化外,还应加强热带气旋外流与环境流场的相互作用,海-气交界面的参数化问题,热带气旋结构变化与TC强度变化关系以及这种关系的物理本质的研究,通过深入研究,认识热带气旋强度变化的物理机制,提高热带气旋强度变化的预报能力。
The study on the change in tropical cyclone intensity has attracted more attention. Significant progresses have been made in the subject since 1995. This paper summarizes the achievement of research in the change in intensity of tropical cyclone made in recent years. It mainly include （1） the achievements of tropical cyclone genesis and its maximum potential intensity; （2） the effects of gradient of planetary vorticity, environmental uniform flow, vertical shear of environmental flow and the interaction between the outflow of tropical cyclone and enveironmental flow on the change in intensity of tropical cyclone; （3） the relationship between the change in the structure of tropical cyclone and its intensity variation, particularly in the field of asymmetric structure induced by the environment flow, the application of verifying of the theory of the slant vorticity development and theory of vorticity Rossby wave in the change in tropical cyclone inteensity; （4） summarizing the the role of the thermal regime of ocean and sea spray on the change in intensity of tropical cyclone. It is concluded that although the obvious progress has been made in recent years, there are many challenges in the field of the change intensity of tropical cyclone. SCAT and cloud track retrieved wind in the research strengthened. Besides, more attention has been paid to The application of satellite data such as AMSU, Quik of the change in tropical cyclone intensity should be the interaction between the outflow of tropical cyclone and the trough of mid-latitude, the initial field of the ocean-atmosphere coupled model, the parameterizations of interface of ocean and atmosphere, and the mechanism of the effect of structure change of tropical cyclone on its intensity. It is expected that the results of researches may promote understanding of the change in tropical cyclone intensity and improve the intensity forecast skill.
