Based on the observation data of automatic weather station, LAP-3000 wind profile radar and radiosonde data of Jiuzhaigou - Huanglong Airport (hereinafter referred to as Jiuhuang Airport), the wind field characteristics of Jiuzhaigou Airport and the relationship between high altitude wind and low altitude wind are discussed.??The analysis shows that the westerly wind mainly occurs in December, January-March and June-September, and when the temperature is low and the wind speed is high, the westerly wind is easy to appear in the airport after morning.??The research results can provide theoretical basis for the meteorological conditions of plateau airport, help Jiuhuang Airport to understand the characteristics and laws of the gale process, reduce the stopping of aircraft approach due to turbulence, and thus improve the utilization rate and operation efficiency of the airport.
