摘要
为了正确认识茅台机场平流雾特征及其对机场飞行安全的影响,利用机场地面观测资料,对2017年11月—2021年6月的平流雾事件的时序变化特征及气象要素特征进行分析。结果表明,平流雾事件主要发生在11月至次年1月,明显日出前后发生频率较高,下午到日落时发生频率最低。机场盛行110°左右风和290°左右风,290°左右风与平流雾形成密切相关,尤其在平流雾高发期间,风速越大、湿度越高,能见度越差。温度在5~10℃时,平流雾能见度最差,气温低于0℃时,能见度有转好的倾向。
In order to correctly understand the characteristics of advection fog at Moutai Airport and its impact on flight safety,the temporal variation characteristics and meteorological features of advection fog events from November 2017 to June 2021 were analyzed using the ground observation data of Moutai Airport.The results show that advection fog events mainly occur from November to January of the following year,with obvious diurnal variation characteristics.The frequency of advection fog events is higher around sunrise,and the frequency of advection fog events is lowest from afternoon to sunset.The prevailing wind of the airport is about 110°and about 290°,and the wind of about 290°is closely related to the formation of advection fog,especially during the high occurrence of advection fog,the greater the wind speed and the higher the humidity,the worse the visibility.When the temperature is 5~10℃,the visibility of advection fog is the worst,and when the temperature is lower than 0℃,the visibility has a tendency to improve.
