利用美国能源部大气辐射测量计划移动观测设备-地基云雷达在我国寿县地区2008-10-15~2008-12-15的观测资料，对云的出现频率和宏观特征进行了统计分析。统计结果表明：寿县地区秋末冬初云出现频率最大值的时间和区域主要在06：00~09：00(UTC)(即北京时间14：00~17：00)的近地面附近，其次是在04：00(UTC)和23：00(UTC)的8 km高度附近，并且云出现频率最大值时所对应的平均反射率因子最小。云层的出现频率以单层云居多，占全部云层的62.9%，双层云占29.8%，还有少量的多层云。云类型的出现频率以卷云、高层云和层积云居多，分别占30.9%、26.5%和22.2%。

By means of observation data detected by atmospheric radiation measurement mobile facility called ground-based cloud radar of the U.S.department of energy (DOE)in Shouxian county in the east of China from October 15 to December 15,2008,the occurrence frequency and macro-property of the cloud are analyzed.The results show that the maximum of cloud occurrence frequency is near the ground at 06-09 UTC (14-17 GMT)in Shouxian area in late autumn and early winter,and it also occurs near the height of 8 km at 04 UTC and 23 UTC.Moreover,the maximum of cloud occurrence frequency corresponds to the minimum of the average reflectivity factor.The frequency of cloud layers is in the majority with single cloud,accounting for 62.9% of all clouds,and double clouds account for 29.8%,which also exists a small amount of multi-layer clouds.The frequency of cloud types is given priority to cirrus,altostratus and stratocumulus,accounting for 30.9%,26.5% and 22.2%respectively.
