影响新疆铁路设计运营的灾害性天气空间分布规律研究

The Spatial Distributions of Disastrous Weather Influencing on the Design and Operation of Xinjiang Railway

文章采用新疆地区1961—1999年39年中87个气象站的气象资料,分析了影响新疆铁路运营的主要灾害性天气的空间分布规律。结果表明:(1)影响新疆地区铁路设计、建设和运营的主要灾害性天气为大风、沙尘暴、暴雪。而大雾和雷暴天气,对新疆铁路设计、建设和运营的影响则相对较弱。(2)北疆地区、伊犁河谷地区,主要受暴雪、大风、雷暴、大雾的影响。(3)南疆地区、吐哈盆地地区,主要受沙尘暴和大风天气的影响。

Adopts the meteorological date of 87 weather station in Xinjiang at 1961-1999, analyzes the spatial distribution of the main severe weather affecting the Xinjiang railway. The results show that ： （ 1 ） Strong winds, Sandstorm and Blizzard are the main severe weather affecting the Xinjiang railway design, construction and operation. （2）The region of Northern Xinjiang and Ili river valley mainly influenced by Blizzard, Strong winds, Thunderstorms and Fog. （3）The region of Southern Xinjiang and Turpan-Hami Basin mainly influenced by Sandstorm and Strong winds.
