| 摘 要： | 应用基本气象观测资料和NCEP/NCAR再分析资料,对2006年4月16—17日发生在内蒙古的一次区域性的大风沙尘暴天气过程,从天气学成因、动力机制、物理量场等方面进行了分析。结果表明：蒙古气旋是这次沙尘暴天气的主要影响系统;蒙古气旋的强烈发展和冷锋后大风是起沙的主要动力;前期持续增温使得低层大气处于不稳定层结;中低层强的上升气流及低层强辐合,为沙尘暴爆发提供了有利的抬升,有利于沙尘的起沙及远距离传输。 |

| Abstract: | By using observation data and the NCEP/NCAR reanalysis data,a severe dust storm with strong wind occurred in Inner Mongolia on April 16,2006 was analyzed based on meteorology cause,dynamic mechanisms,physical quantity field and other areas.The Results showed：Mongolian cyclone was a major effect system of the sand-dust storm,the intensive development of Mongolia cyclone and the strong wind caused by the cold front was the main power of sand emission,the early sustained elevated temperature caused the lower atmosphere at unstable stratification,the updraft between the lower and middle and strong convergence at low level provided a favorable elevation condition,was conducive to dust emission and long-distance transport of sand. |
