摘要
利用常规观测资料,对2005年3月9日至11日忻州市大范围的强降温和大风天气过程的成因进行了诊断分析。结果表明:500 hPa横槽转竖并东移后,引导冷空气大举南下,是产生强降温天气的必要条件;高空横槽、地面冷锋和蒙古冷高压是寒潮过程的主要影响天气系统。
The use of information systems and conventional micaps data on the March 9 to 11 Xinzhou City, a wide range of strong winds and cool weather during the causes of the diagnosis and analysis. The results showed that： 500 hPa vertical and horizontal shafts to the eastward shift, the guide massive cold air southward, this is a necessary condition for strong cooling. High-altitude horizontal shafts, ground cold front and Mongolia cold high-pressure cold wave this process is the main weather systems.
