Cyclolysis versus Frontogenesis

[摘要] During the recurvature typhoons increase in strength and their progressive movement slackens. After the recurvature they travel to the eastward, and decrease in strength, travelling at a great rate In this stage, the tropical revolving storms become gradually oblong and decre se in strength.According to the Norwegian School, the warm-sector cyclones deepen with an unaccelerated celerity as the occlusion process proceeds regularly, and from the time when the cyclone is occluded there is a very slow and gradual change from the deepening to filing. But the final stage of tropical cyclones differs much from that theory. In this stage, corresponding to the cyclolysis-frontogenssis, tropical cyclones deform from symmetric to asymmetric with appreciable filling.
