选取2002年1月至2010年6月银川河东机场气象台收到的有关低空风切变的话音方式的航空器空中报告,对本场附近35起飞机报告的因风切变导致复飞或返航事件的气候特征及发生低空风切变的大气环流形势进行了统计分析,初步认为本场低空风切变易发生在春季（3～5月）,11：00～14：59及16：00～17：59时段,此时正是本场进出港航班最密集的时段,因此对本场低空风切变的研究对保障飞行安全有重要意义。同时,发现风切变的发生主要与5种主要的高空形势3、种地面形势及宁夏北部地面切变线的存在有密切关系。

The 35 typical cases about low-level wind shear over Yinchuan Hedong Airport from Jannuary 2002 to June 2010 were selected from the voice way aircraft report,and the circulation situation resulting to low-level wind shear there was analyzed statistically.The results showed that the low-level wind shear weather occurred easily in spring（March to May） and during the period of 11：00-14：59 and 16：00-17：59,when was the most dense flights entering or leaving ports in Yinchuan Hedong airport,so the study of low-level wind shear had significance to flight safety guarantee.The occurrence of low-lever wind shear was closely related to five kinds of upper-lever situations,three kinds of ground situation and the ground shear line in northern of Ningxia.The use of circulation pattern,local climatic character and conventional observation data were beneficial to giving out early warning of low-level wind shear.
