Characteristics of low-level wind shear in Qinghai Xining Airport are analysed by using pilot reports and reanalysis data. It manifests seasonal and diurnal variation that the frequency is higher in spring and summer, and for diurnal variation, it is higher in afternoon and early night. The weather patterns of low-level wind shear can be roughly divided into four types. Their characteristics are also studied in this paper. And terrain effect is of importance to the cause of low-level wind shear, gorges and mountains lead to strong wind and variable wind direction.
