摘要

基于2000年以来登陆广东的9个强台风过程的逐时观测资料和灾情数据，分析了强台风登陆过程中大风的时空演变、分布、成因及与倒塌房屋的关联，发现：（1）9个强台风在登陆前的逐时最大风速全部出现在第一和第二象限，登陆后则有77.6%的时次最大风速出现在第四、第一象限；10级以上大风主要分布在台风路径右侧的沿海地区，持续时间在10-24 h之间，有4个台风的12级以上大风维持了8-13 h；（2）以大风范围和维持时间构建的各等级大风“站时”来表达大风的综合影响程度，发现登陆前大风“站时”样本出现频率明显大于登陆后；（3）登陆台风经过的下垫面显著影响大风深入陆地的距离和维持时间，台风路经水陆交汇地区或平缓下垫面的，其大风深入陆地较远；（4）倒塌房屋数量与台风登陆时中心气压、最大风速、影响范围、维持时间、大风“站时”等均有关联，其中与12级以上大风参数关联度最高。

Abstract

Based on the hourly-observed weather data and disaster data of nine strong typhoons landed in Guangdong province since the year 2000

the spatial and temporal evolution

distribution

and causes of gales as well as their relationship with collapsed houses are analyzed. The results show that: (1) Hourly maximum wind speeds of nine typhoons are all in the first and second quadrants before the landfall

after which 77.6% of them fall in the fourth and first quadrants. Gales of force 10 and above are distributed mainly in the coastal areas and on the right side of typhoon tracks with durations between 10-24 h. In addition

gales of force above 12 lasted 8-13 h in four typhoons. (2) The influence of gales is expressed by the "station-hour" based on the ranges and durations of gales. It is found that the "station-hour" samples of gales mainly appeared before the landfall. (3) The underlying surface has a significant effect on the distance and duration of the typhoon gales penetrating into the land. When the typhoon passes through the intersection area of land and water or the gentle underlying surface

the wind penetration to the land is larger. (4) The number of collapsed house is correlated with the central pressure

maximum wind speed

influence range

maintenance time

and "station time" of typhoon gales

especially with those of gales with force 12 or above.
