Abstract: Based on the ground meteorological observation data from 1955 to 2016 in Jingzhou Meteorological Station, the meteorological conditions in the preselected area of Jinan General Airport were statistically analyzed by means of linear trend, comparative analysis and other methods. The results show that pre-selected site area of Jinan General Airport has a low annual average wind speed, with an average monthly wind speed of 1.9~2.5 m/s. The annual static wind frequency is high, which is 18.2%, and the frequency of wind speed of 0~5.0 m/s is 89.99%. The airport pre-selected sites has few days with low visibility, the average days of the visibility, the annual average number of days with visibility less than 800 m, 800~2 000 m, 2 000~4 000 m is 9.8, 10.8,13.7 d, respectively. The average days of the torrential rain, strong winds, thunderstorms, hail, sand storms and other weather disasters is 3.30, 3.98, 32.20, 0.49, 0.02 d. The probability of high impact weather is lower than that of Wuhan Tianhe Airport. There are many favorable conditions and less unfavorable conditions in the pre-selection site. The influence of adverse conditions on flight can be avoided by improving the accuracy of prediction and the professional quality of management and operator.
