| 摘 要： | 本文以内蒙古阿拉善盟范围内的巴彦浩特、拐子湖等9个气象台站1961年~2004年的沙尘暴逐次统计数据和气象资料为依据,利用Excel和SAS数据处理软件,采用线性趋势估计、相关分析、多元回归等方法,对大风、降水、气温等主要气象因子与沙尘暴发生的次数和强度的关系进行了系统研究,结果表明阿拉善地区沙尘暴发生的日数与大风日数呈显著正相关;沙尘暴日数与年降水量呈显著负相关;沙尘暴发生日数与气温相关性最弱,呈负相关。

| Abstract: | The data on sandstorm and meteorology in 9 weather stations,such as Bayanhaote and Guizigu,in Alashan League were used to analyze the relationship between wind,precipitation,temperature and the frequency and intensity of sandstorm.Linear trend analysis,correlative analysis and multivariate regression were made with Excel and SAS software in the dada analysis.The results showed that the days of sandstorm are significantly positive correlation to the days of wind, and significantly negative correlation to the annual precipitation,and the weak negative correlation to the air temperature. |
