Abstract
To solve the lack of wind speed observation in the planning and construction of railway in remote areas,this study uses high resolution WRF model's simulation to study gale wind disasters.The result shows that the WRF's wind speed can generally capture the wind speed's spatial patterns in Xinjiang complex terrain.In 1979 ～2013,the mean days with gale wind reflects that Sanshili wind region,Baili wind region and Nanjiang Sanshili wind region along the constructed Lanxin Railway and Nanjiang Railway have more strong wind days than other regions in Xinjiang.The railways on planning have more strong wind days only in mountainous region with complex terrain.All regions except Baili wind zone tend to have more gale days.The gale wind index analysis shows that most sections of the planned railways,such as Luohe Railway,Kuge Railway,Hajiang Railway and Keta Railway are located in regions with higher gale wind index with increasing rate of 8 m/s per 10 years.关键词
