摘　　要：广汉机场作为中国民航飞行学院在四川的训练基地之一,承担着初、中教机及高教机的飞行训练任务。春季午后机场跑道常出现非系统性阵风,给本场初、中教机学员的单飞训练带来安全隐患。本文通过对广汉机场2018~2022年春季3~5月逐小时地面10 m高度10 min平均风速进行统计发现:1)广汉机场春季偏北风出现的频率明显多于偏南风,飞机在起飞着陆过程中更容易遇到左侧风影响,需注意修正;2)3~4月盛行风向以正北风最多,其次为东北偏北风和西北偏北风,偏南风分量出现频次较少;到了5月之后,盛行风向有顺时针的偏转,以东北偏北风为最多,其次为东北风,且偏南风出现的频率明显高于前2个月;3)广汉机场春季地面逐小时10 min平均风速呈“单峰型”分布特征,需注意机场午后14~16时的地面风速变化情况,并及时向塔台通报。As one of the training bases of the Civil Aviation Flight University of China in Sichuan,Guanghan Airport undertakes the mission of flight training for primary, intermediate and advanced trainer aircraft. Unsystematic gusts of wind often appear on the airport runway in the afternoon in spring, which brings safety hazards to solo training of junior and middle flight students. Based on statistics of average hourly wind speed at 10 m above the ground for 10 minutes during March to May at Guanghan Airport in the spring of 2018-2022, this paper finds that: 1) the frequency of northerly winds at Guanghan Airport in spring is significantly more than that of southerly winds, and aircraft in the process of take-off and landing is more likely to encounter left-side winds and needs correction. 2) During March to April the prevailing wind is mostly northerly wind, followed by northeasterly wind and northwesterly wind, and southerly wind component occurs less frequently;After May the prevailing wind direction has a clockwise deflection with NNE wind being the most, followed by northeasterly wind, and the frequency of southerly wind is obviously higher than that in the previous two months. 3) It is characterized by a “single peak” distribution. It is necessary to pay attention to the change of ground wind speed at the airport during 14: 00 to 16: 00. and report it to the tower in time.
