摘要： 沙尘天气是一种非常严重的灾害性天气现象,给工农业生产、交通运输、居民生活和空气质量带来不利影响。2010年3月我国共出现了6次沙尘天气过程,次数比近10年同期(4.2次)偏多,其中强沙尘暴天气过程1次、沙尘暴天气过程3次、扬沙天气过程2次,具有发生时段集中、首发时间偏晚、影响范围广泛等特征。分析表明:在气候变化和沙尘源地等地理背景之下,气温回升、降水偏少、冷空气势力强、蒙古气旋强烈发展等气象条件是2010年3月我国沙尘天气偏多、偏晚的主要原因。

Abstract: Sandstorm is a kind of serious disastrous weather and results in some disadvantageous impacts on industrial and agricultural production, traffic, people's daily life and air quality.
