中文摘要:
   利用2007—2010年CloudSat卫星资料,对青岛地区(35.583°~37.150°N,119.050°~121.000°E)云特征参量进行了统计分析。结果表明:单层云出现频率为39%左右,多层云主要以2层云为主,出现频率均为18%左右;月平均云量在64.1%~77.6%之间,从1月至12月呈递减趋势;卷云、高层云、高积云和层积云平均频率之和为86.5%,其他类型的云出现的频率均不高;云水路径在4、5月和8、9月较大,分别达到了200 g·m-2以上和350 g·m-2以上;云液态有效粒子半径在6~16 μm之间,春、夏、秋季高值区位于云体中部至上部;云冰晶有效粒子半径在20~120 μm之间,高值区位于云体中部至底部;青岛南部,即近海区域云有效粒子半径和云水含量大于北部。
英文摘要:
   The parameters of cloud characteristics in Qingdao area (35.583~37.150°N, 119.050~121.000°E) are analyzed using the CloudSat 2B dataset from 2007 to 2010. The results show that the frequency of single-layer cloud is about 39% and multilayer cloud is mainly double-layer cloud whose frequency is about 18%; the monthly mean cloud fraction is between 64.1% and 77.6%, which shows a declining trend from January to December; the total average frequency of cirrus, altostratus, altocumulus, and stratocumulus is 86.5%, while the frequencies of other types of cloud are all not high; the cloud water path is relatively large in April/May and August/September, reaching over 200 g·m-1 and 350 g·m-1, respectively; the effective particle radius of liquid cloud is between 6 and 16 μm and the high value area in spring, summer, and autumn is located from middle to upper part of the cloud; the effective particle radius of ice cloud is between 20 and 120 μm and the high value area is located from bottom to middle part of the cloud; furthermore, the cloud effective particle radius and cloud water content in the southern offshore areas are greater than those in the northern area of Qingdao.
