摘　　要：通过对一次影响珠海机场航班调控和飞机起降的平流海雾过程进行天气形势、温湿条件、风廓线特征分析,结果表明：（1）850hPa以下持续暖湿平流是平流雾形成的基础;（2）近地层逆温及中低层多层逆温的温度层结和近地层的饱和湿层,以及适宜的地面风场是形成平流雾的有利条件,夜间的辐射冷却加强了贴地层大气的饱和度而形成平流雾;（3）风廓线资料分析表明边界层内东南～偏南风场保证了暖湿平流条件,而近地层偏北风干冷平流入侵并出现下沉气流、逆温层被破坏使雾趋于消散.Based on an impact of zhuhai airport flight control and aircraft take-off and landing of the weather situation for the process of sea advection fog, temperature humidity conditions, wind profile characteristics analysis, the results show that： （1） below 850 hPa continued warm wet advection is the basis of the advection fog formation; （2） the surface layer of inversion and the lower layers of inversion temperature stratification and nearly saturated wet layer formation, and suitable the ground wind field is the favorable conditions of forming advection fog, radiation cooling strengthened the ground layer in the night by southeast the saturation advection fog atmosphere; （3） the wind profile data analysis showed that the toward south wind field in the boundary layer ensure the conditions of warm wet advection, in the recent formation toward north dry wind invasions and sinking airflow appearance, the inversion layer was damaged to the fog dissipation.
