| 摘 要： | 基于北京机场1971-2000年逐时地面气象观测资料，对北京机场30a来出现的灾害性低云进行了统计，总结出北京机场灾害性低云变化的客观规律，同时对这30a中出现灾害性低云的典型天气形势进行了分析整理。结果认为，冷锋前和高压后等天气过程是产生灾害性低云的主要天气形势，且灾害性低云发生时，多伴随高湿、低能见度等天气条件。对各种气象要素对灾害性低云的影响做了进一步分析，以期对机场实际预报工作起到一定的指导作用。

| Abstract: | Based on the statistics of meteorological observations at Beijing airport during 30 years from 1971 to 2000,the objective laws of disastrous low cloud are summarized.The typical weather situation of disastrous low cloud during these 30 years has analyzed and arranged.The results show that disastrous low cloud is mainly caused by cold front and back pressure,which always occurs followed with high humidity,low visibility and other weather conditions.This paper makes a further analysis for the effect of various meteorological elements on disastrous low cloud,which may play a role in guiding the practical airport weather forecast. |
