| 摘 要： | 以锡林郭勒地区沙尘暴高发季节15个气象站1961-2008年春季(3-5月)的气象资料为数据源,分析沙尘暴发生的时空分布规律及气象因子对锡盟春季沙尘暴发生的影响,结果表明:春季沙尘暴发生频次与大风、前期降水量等气象因子有关;另外,沙尘暴的发生与蒙古气旋这一特定的天气系统间存在一致的变化趋势。掌握沙尘暴分布规律及其与气象因素的关系,在预报和监测沙尘暴工作中具有重要的实际意义。

| Abstract: | Using the meteorological data of 15 weather stations in spring(March to May) which was the high occurrence season of sand-dust storm from 1961 to2008,the space-time distribution law and the influence of weather element on sand-dust storm occurrence were analyzed.The results showed that the occurrence frequency was connected with weather factor that include gale,earlier stage precipitation and so on.In addition,the variation trend of sand-dust storm occurrence was coincident with specific weather system whic... |
