不同路径进入广西内陆台风气候特征分析

Climatic Characteristics of Typhoon into Interior Guangxi from Different Paths

广西是我国受台风影响最多的地区之一,以不同路径进入广西的台风,造成的影响也有所不同。该文应用1970-2013年翔实的台风资料,对进入广西的三类路径(沿海型、桂东南型和桂东北型)台风进行统计分析。结果表明:从桂东南进入广西内陆的台风最多,造成的强降雨影响最严重;从沿海进入广西内陆的台风,所带来的灾害性大风范围最广,其造成特大型灾害和大型灾害的频率最高;而从桂东北进入广西内陆的台风,对广西造成的风雨影响是三类路径台风中最弱的,其所造成的灾害主要是中型灾害。这一分析结果对促进广西台风的预报和服务以及防台减灾工作将产生有益的影响。

Guangxi is one of the areas that affected by typhoon mostly in China.The influences of typhoon from different paths into Guangxi can be different.Based on detailed data on typhoon during 1970-2013,typhoon into Guangxi from three paths（along the coast,Southeast of Guangxi and Northeast of Guangxi） are statistically analyzed.Results show that typhoon into Guangxi inland from Southeast of Guangxi is the most,and the influence of rainfall it caused is most serious.Typhoon from the coast into the interior Guangxi trigger strong winds of the widest range,are with the highest frequency of resulting in large disasters and large-scale disasters.Typhoon from the Northeast Guangxi into Guangxi,have the weakest storm impact among the three ways on Guangxi,mainly cause disasters of medium size.The results of the analysis will have beneficial influence on the forecast and service of typhoon into Guangxi and the work of typhoon prevention and disaster reduction.
