摘要
使用2011-2016年中国内地台风灾情数据和地面气象站数据,基于154个台风灾害案例,回算台风影响期间受灾地区的风雨情况,统计分析台风灾害时空特征及各项灾损与气象要素的关系。结果表明,8月是中国内地发生台风灾害次数最多的月份,各项灾害损失也最重;浙江省的主要台风灾损是人口受灾,广西、福建的主要台风灾损是房屋倒塌。受灾人口数、农作物受灾面积与台风大风和降雨均有关,与极大风速的相关性最高。房屋倒塌主要与台风降雨有关,与最大日雨量的相关性最高。人口损失主要受台风降雨影响,与最大日雨量和暴雨站点比例显著相关;房屋倒塌和洪水可能是台风造成人口损失的重要中间因素。
By using typhoon disasters data and surface weather station data during 20112016 in China's Mainland,the wind and precipitation situations of the regions are calculated based on 154 typhoon cases,and the spatio-temporal characteristics of typhoon disasters and the correlation between losses and meteorological parameters are statistically analyzed.The results show that August is the month with the largest number of typhoon disasters in China's Mainland and the heaviest loss of various disasters.In Zhejiang,the main typhoon disaster is that the population is affected,while the main typhoon disasters in Guangxi and Fujian are the collapse of houses.The number of affected population and affected area of crops are related to both the typhoon wind and precipitation,with the highest correlation with the maximum wind speed.The number of collapsed houses is mainly related to the typhoon precipitation,with the highest correlation with the maximum daily rainfall.The number of casualties is mainly affected by the typhoon precipitation,with significant correlation with the maximum daily rainfall and the proportion of rainstorm stations.Collapsed houses and flood caused by heavy rainfall are likely to be important intermediate factors in the casualties caused by typhoons.
