近70年来影响金华的台风气候特征及降水分布特点
Climatic characteristics and precipitation distributions of typhoons affecting Jinhua in the past 70 years
摘要
Abstract
An analysis of the climatic characteristics of typhoons affecting Jinhua over the past 70 years reveals that,a total of 164 typhoons impacted Jinhua from 1953 to 2022,averaging 2.3 per year.In the 1960s,2000s,and 2010s,the annual mean numbers are around 2.7,whereas in the 1980s and 1990s,the annual mean numbers are relatively low(around 2).Typhoons affecting Jinhua occur between May and November,with July to September accounting for 82.7%of the annual number.Severe typhoons mainly occur in August and September,with the highest frequency in late August and middle September.In October,severe typhoons account for as high as 44.4%,which is the highest proportion.75%of the typhoons affecting Jinhua are landfall typhoons,with 85.2%of the total number landing in Zhejiang and Fujian provinces.Typhoons that land from the northern central Fujian to the southern central Zhejiang have the highest impact on Jinhua,accounting for 41.7%of the typhoons which cause severe or larger impacts,with those landing in the southern central Zhejiang causing particularly severe impacts at a rate as high as 64.2%.Typhoons turning eastward from 125°E have small impacts on Jinhua,while typhoons moving northward along the coast have relative large impacts on the eastern Jinhua,such as Typhoons 6910 and 1509.By categorizing typhoons affecting Jinhua from 2010 to 2022 according to different tracks,and analyzing the precipitation distribution,it is found that the precipitation distribution of typhoons relates to the topography of Jinhua,indicating a significant effect of terrain on precipitation.关键词
