| 摘 要： | 根据天气特点、热力作用，雷达回波、地形等方面对乌海机场2005年5月26日、2006年7月24日发生的两次强沙尘暴天气进行分析，分析结果表明，造成这两次沙尘暴的天气形势均为西北气流型，由于上游沙漠地带地表温度高，低层热动力辐合抬升，导致下地表出现上升运动，造成沙尘暴天气。

| Abstract: | Based on synoptic characteristics,thermodynamic effect,radar echo,topography,etc.,twice heavy sandstorm weathers occurred in Wuhai Airport on May 26,2005 and July 24,2006 were analyzed.The results showed that the synoptic situation that led to the two sandstorm weathers was northwest airflow pattern,because the desert surface temperature of upper reaches was high,low level convergence uplift,led to ground surface at-mosphere occur to ascending motion,in sandstorm weather. |
