| 摘 要： | 本文通过对白云机场附近近年多起低空风切变的大气环流形势进行了统计分析，发现风切变的发生与高压脊、脊后槽前、锋面低槽和热带气旋环流4种主要天气形势密切相关。预报业务中利用这4种分型对提前发布低空风切变预警趋势，确保飞行安全有一定的参考价值。

| Abstract: | This paper analyzes the general circulations of the cases in recent years when the low level wind shear occurred near Baiyun airport. The result shows that four types of synoptic situations have a close correlation with the occurrence of the wind shear. They are pressure ridge, behind ridge and ahead of trough, frontal trough and tropical cyclonic circulation. In the forecasting operation, these four types of general circulations can provide a good reference for issuing wind shear warning in advance which assures the aviation safety. |
