摘　　要：Based on the hourly observation data of heavy rainfall at Changbei Airport from 2011 to 2018,the main characteristics of heavy rainfall at the airport were analyzed. The results show that the heavy rainfall at Changbei Airport often occurred from April to August,most in June,mostly from the evening to midnight. Visibility and runway visual range( RVR) were often affected by the heavy rainfall,but the proportion of weather processes below the take-off and landing standards was relatively small. The main influencing factors of heavy rainfall were low vortex shear,front,high trough and subtropical high edge. The changing characteristics of meteorological elements in the high-centroid rainfall processes were more obvious,and they had greater impact on flight.
