利用1961—2010年淖毛湖站的气象资料,分析了50a来气温、降水、风速、大风日、沙尘暴的变化特征,结果显示淖毛湖年、冬季、夏季气温均呈上升趋势,20世纪80～90年代冬季增温强于夏季,进入21世纪夏季升温最为明显,冬季却降温最为明显,但总体平均来看,冬季增温强于夏季;降水总体趋势上升,90年代以后降水明显增多,但仍然比较干旱;风速及大风日数总体趋势下降,20世纪60年代中期到80年代为多大风时段,90年代后年平均风速和大风日数明显减少;20世纪60年代中期到70年代沙尘暴日数呈现急剧增加趋势,80年代后沙尘暴日数呈现急剧下降趋势。表明淖毛湖气候正在趋向变暖,特别是2001年以来该区域气温急剧升高,使得高温、干旱、多大风成为淖毛湖气候的突出问题。

Using the meteorological datafrom 1961 to 2010 of Naomaohu station,the variation characteristics of temperature,precipitation,wind speed,sand storms were analyzed.The results showed that the temperature in year,in winter and in summer took an upward trend,and the increase rate of temperature in winter was more obvious than that in summer.The precipitation has increased especially since the 1990s,but the place was still relatively dry.The wind speed and the gale frequency after 1990s were significantly reduced.The sand storm frequency was rapidly increased from mid-1960s to 1970s and sharp declined after 1980s.The climate has inclined to warming especially since 2001,making the high temperature,drought,much gale become outstanding problems in Naomaohu.
