Based on the hourly meteorological observation data of Guiyang Longdongbao International Airport from 2008 to 2022 and the flight operation data from 2020 to 2024, this paper systematically analyzes the temporal and spatial distribution characteristics of complex weather conditions such as thunderstorms, low clouds and low visibility, ice and snow freezing, strong winds, and wind shear, as well as their impact mechanisms on flight operations. The study finds that thunderstorms mainly occur in the afternoon and night from May to August, low clouds and low visibility are dominated by winter radiation fog and frontal fog, ice and snow freezing mostly happen from December to February of the following year, and strong winds and wind shear frequently occur in spring. Severe convective weather is the main cause of flight diversion and return (accounting for 72%), while low clouds and low visibility and ice and snow freezing significantly increase the risk of flight delays (accounting for 49% and 18% respectively). In combination with the airport operation standards, targeted suggestions such as optimizing low visibility operation procedures, strengthening seasonal weather warnings, and improving runway de-icing strategies are proposed, providing a scientific basis for meteorological services and flight scheduling at complex terrain airports in the southwest plateau. %K 贵阳机场， %K 复杂天气， %K 航班运行， %K 气象服务， %K 保障建议
