| 摘 要： | 分析了热带风暴"黄蜂"在登陆过程中逐小时高分辨红外云图上的螺旋云带及其强对流云团的变化规律.从强对流云团发展为主螺旋云带的演变过程中,螺旋云带主要表现为其前端的对流逐渐加强,其余部分逐渐减弱,以及前端的强对流云团总体表现为旋入运动且维持时间较长,而其余部分的云团总体表现为远离中心等的特征.初步探讨了螺旋云带结构变化与风暴强度之间的关系和"黄蜂"在登陆后迅速减弱的可能原因.

| Abstract: | We analyse spiral bands and their strong convective clouds of tropical storm Vongfong during landfall by using hourly GMS infrared images. It is featured by increasingly intense moist convection in the forepart of a spiral band but weakening moist convection in the rear part, when a strong convective cloud develops into a main spiral band. The relation between the structure variation of spiral bands and the intensity of the storm is discussed, and possible reasons that Vongfong rapidly weakens after landfall are studied. |
