| 摘 要： | 近年来,内蒙古自治区建立了6个沙尘暴监测站,对沙尘天气进行了连续、定量观测,在预报业务工作中可以得到器测能见度、PM10、TSP等定量数据,为沙尘暴的定量分析和预报提供了基础条件.选取了2004-2007年间内蒙古地区10次较强沙尘暴天气过程,利用内蒙古自治区的6个沙尘暴监测站器测资料,结合常规观测资料进行了分析.分析表明:器测数据具有连续、稳定、定量的优势;但器测数据与现行沙尘天气业务标准存在很大差异,需要新的分级标准.在现有数据条件下,初步确定了器测能见度、PM10的沙尘天气分级标准;讨论了沙尘暴形成的定量条件和机制,以沙尘综合指数、摩擦速度等为预报因子建立了器测能见度、PM10的沙尘暴定量预报方程.该预报方法在2008年的业务试用中预报效果较好.

| Abstract: | In recent years, the Inner Mongolia Autonomous Region has established 6 sand storm inspection stations. A series of quantitative data, such as the instrument-measured visibility, PM10, TSP was obtained from the continuously quantitative observation in the sand dust weather. It provides the basic requirement for the sand storm quantitative analysis and forecast. Ten strong sand storm processes in Inner Mongolian during 2004-2007 are chosen, and the instrument-measured data of 6 sand storm inspection stations... |
