摘要: 利用荆州气象站1955—2016年的地面气象观测资料,采取线性趋势、对比分析等方法对荆州纪南通用机场预选场址区域的气象条件进行统计分析。结果表明,荆州纪南通用机场预选场址区域年平均风速低,月平均风速1.9~2.5 m/s;年静风频率高,为18.2%,风速等级0~5.0 m/s频率为89.99%;低能见度日数少,出现小于800 m、800~2 000 m、2 000~4 000 m的能见度天气的年平均日数分别为9.8、10.8、13.7 d;暴雨、大风、雷暴、冰雹、沙尘暴等灾害天气年平均日数分别为3.30、3.98、32.20、0.49、0.02 d;高影响天气出现几率低于武汉天河机场;气象有利条件多,不利条件少。可以通过提高预报准确率和管理及操作人员的专业素质避免不利条件对飞行的影响。

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.

Key words: airport, pre-selected site, meteorologic condition, high impact weather
