Air-cooling denotes air-cooling replacing water-cooling in power plant.The consumption of cooling water in air-cooling system is only 20%~35%of that in water-cooling system.Because of its potential in saving water,air-cooling is undoubtedly the best cooling way of fire power station in Xinjiang,where the water resource is extremely deficient.The analysis and research on the air-cooling meteorological parameter is the guide of Xinjiang electrical base construction.It offerred design index of meteorological parameter,and concerned concretely influence the evaluation of future climate change,and ecological environment.This paper introduced the compositon of air-cooling observation station and the application of air-cooling meteological parameter analysis and research into air-cooling project.
