西北太平洋台风路径与台风云型之间的关联性分析
Analysis of the correlation between typhoon tracks and typhoon cloud scene types in the Northwest Pacific
摘要
Abstract
In recent years,the technique of estimating typhoon intensity using typhoon cloud scene types has been widely used in operational forecasting,but whether the cloud scene types correlate with the typhoon track has not been analyzed.In this paper,typhoons occurring in the Northwest Pacific during the four-year period of 2019-2022 are selected,and the cloud scene type data obtained based on the advanced Dvorak technique are used to analyze the frequency of six types of cloud scenes at different stages of the typhoon's life span,as well as the characteristics of cloud scene types occurring at different typhoon movement directions.The results show that all types of cloud scenes may appear when the typhoon is moving toward the northwest,and each type of cloud scene has the possibility to appear in any moving direction,but each type has its most likely mainstream moving direction.The occurrence of different cloud scene types varies with seasons,and their frequency also changes when the typhoon experiences a sudden shift in its track during its life cycle.As the intensity of a typhoon increases,its movement direction alters,and the dominant cloud scene types appearing in its moving directions also change.During the tropical depression stage,cloud scene mainly reflects the asymmetric structure of the typhoon.Once the typhoon reaches its full intensity,the cloud scene shifts to a more symmetric structure,and the track becomes more concentrated in the northwest direction.This indicates that there is a coevolutionary relationship between typhoon cloud scene types and their intensity and track.关键词
