The Relation Between the Strong Wind Region Along One Hundred Kilometer of Railway and the Topography in Xinjiang
Strong wind is one of the main meteorological disasters affecting the safety in transport and production in Xinjiang, especially in the Bailifengqu area (1.e. the strong wind regions along one hundred kilometer of railway). Because of special type of topography and geomorphy, Shisanjianfang Railway Station is a representative station where the wind is so strong and frequent. According to the narrow pipe effect of mountain pass and the theory of drainage winds after the cold air crosses the mountain, using the actual data measured in recent 2 years, the situations of strong wind appearance were estimated and validated in Bailifengqu area. The results show that in upstream the process of cold air invasion, there is a just 9-10 h delay correlation in wind velocity between upstream Mulei Station and downstream Shisanjianfang Station.
