沙尘暴观测及分级标准研究现状

沙尘暴天气发生时,气流向空中输送大量沙尘,使能见度较低、空气质量恶化,给人们日常生活、身体健康带来严重影响。强沙尘暴往往造成天昏地暗,引起人们恐慌心理,因此,这一天气现象普遍受到社会各界广泛关注。无论是分析研究、预警预报,还是媒体报道,沙尘暴的定义、观测、分级、命名必须规范统一才有可比性、可信性。笔者根据近年来国际上召开的沙尘暴会议文集以及国内出版的有关书籍文献,对沙尘暴观测及分级标准研究的现状作一点综述,并提出一些看法。

Research Status of Sand-dust Storm Observation and Classification Standard

When sand\|dust storm weather is occurring the air current transmits a large amount of sand\|dust into air, which makes the air quality worsening and the visibility lowering, therefore severely influenced the daily life and public health. Especially the heavy sand\|dust storm accompanying darkness often causes public panic so that this kind of weather phenomenon is attracting more attention in recent years. There are various issues on sand\|dust definition, observation, classification and naming. The authors have reviewed the research status on sand\|dust storm monitoring and forecasting as well as the classification standard, according to proceedings of some international conferences and documents published oversea and domestic. Some suggests are given in the paper for the sake of comparability and credibility in the research field of sand\|dust storm.
