| 摘要: |
| 对昌北机场2011—2018年自动气象站逐时降水观测资料进行分析，发现机场区域强降水天气主要特征如下：①昌北机场强降水天气常出现在4—8月，6月最多，多发生在傍晚至上午时段；②强降水过程中，能见度、跑道视程（RVR）常受其影响，但低于起降标准的天气过程所占比率相对较少；③强降水的主要影响天气系统有低涡切变、锋面、高空槽、副高边缘型；④高质心降水过程的气象要素变化特征更为明显，对飞行影响更大。 |

| Abstract: |
| Based on the analysis of hourly precipitation observation data of Changbei Airport from 2011 to 2018, it is found that the main characteristics of heavy precipitation in the airport area are as follows: ① the heavy precipitation in Changbei Airport often occurs from April to August, most in June, mostly in the evening to midnight; ②visibility and runway visual range (RVR) are often affected by the heavy precipitation, but lower than the takeoff and landing standards The main influencing factors of heavy rainfall are low vortex shear, front, high trough and subtropical high edge;④the changing characteristics of meteorological elements in high centroid precipitation are more obvious, which have greater impact on flight. |
