9012号热带气旋维持的卫星云图和垂直结构特征分析

本文根据卫星云图的演变和常规天气分析相结合，对9012号热带气旋登陆后维持水消的成因进行了分析。指出该热带气旋经久不消的重要原因为其西南侧对流云团和东北侧高空槽前对流云带与热带气旋云系相衔接在中低层东北气流引导下卷入，热带气旋内部的两条云带的维持，以及利有的环流条件。

Satellite images and vertical structure feaures sustaised by tropical cyclone 9012

This paper uses satellite images and synoptic data to analyzed the tropical cyclone 90 which sustained long time after landfall. The results show that the important reasons for t cyclon's sustain are the convective clouds at the southwest side of the cyclone,the convecti cloud belts in front of the trough at the northeast side and the cloud system of the cyclon that contact together and involved into the center of this cyclone under the guidance of nort east flow,the long life of the two cloud belts within the cyclone,the beneficial circulation s uation.
