中文摘要	首先对2004年春季最强的一次沙尘天气过程进行了简要分析,然后利用业务化的集成沙尘数值预报系统对其进行了数值预报试验,并在检验了预测结果的可用性的基础上,进一步分析了沙尘浓度、起沙量等模式输出结果的特征.结果表明:该预测系统对沙尘天气的起沙和输送过程预报能力较好;对沙尘天气的发生、发展和消亡过程有预报意义.这次过程的沙尘源地主要是蒙古国南部和中蒙边境沙地,包括毛乌素沙地、腾格里沙漠和浑善达克沙地;起沙和输送过程中各种粒子的贡献随着沙尘天气发生区域的不同而不同,这次过程中起沙量贡献主要是粒径为2～22 mum的粒子,在大气中长时间长距离输送的粒子主要是粒径小于11 mum的粒子.
英文摘要	The strongest dust storms occurred in North China in the spring of 2004 were briefly analyzed, and then the quantitative 72-hour prediction of the dust event was been done by using an integrated operational dust numerical prediction system. The characteristics of the dust event were analyzed based on the validation and reliability of the predicted results, such as dust concentration and vertical dust emission. The results show that the modeling system has the better ability to predict the basic characteristics of the dust events and also offer the predictable information about the whole process, including origination, development and weakening of the dust episode. The dominating dust emission area is the southern part of Mongolia and boundary between Mongolia Gobi Desert and north part of China, including Mu Us Sandy Land, Tengger Desert and Onqin Daga Sandy Land. The particle-size of the particles which offers the biggest contribution to the dust emission is variant with the variety of land surface, but a-mount of particles with diameter from 2-22 f/m is important. The particles with particle-size (d<11 mum) can suspend long time and travel farther than others.
