中文摘要	利用2012年12月至2016年11月A-Train卫星编队中CloudSat卫星与CALIPSO卫星融合产品DARDAR数据对我国西北地区冰云发生概率的水平和季节分布特征,冰水含量和冰云有效半径的垂直分布进行了分析。结果表明,近4年西北地区平均冰云发生率为55.1%,春季冰云出现较多,除河西内蒙古中西部部分地区外,春季冰云发生概率均在70%以上,季节性变化明显。2015年和2016年四季变化浮动比前两年大,四季冰云发生率在西北地区的沙漠区域相对较小,由于特殊地形的影响冰云发生率的高值区出现在青藏高原东北部;青藏高原东北部冰云发生率在春、秋冬季都较大,夏季最小。冰水含量在13 km以上几乎没有冷冰水分布,夏季最大且垂直方向5 km高度下几乎没有分布,秋冬季节冰水含量相对较小,西北各地区之间冰水含量的差异较大,在西北东部季风区分布最少;西北各地区冰云有效半径分布与其冰水含量分布趋势相似,春夏季大,秋冬季小,其中夏季冰云有效半径在5 km高度以下几乎没有分布,由于夏季温度较高,在37°N 39°N冰水含量较大的区域冰云有效粒子半径相对较小。
英文摘要	The Northwest China probability distribution of ice cloud occurrence frequency,ice water content and ice cloud effective radius were presented based on DARDAR data coalesce from Cloud-Aerosols Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) and CloudSat Satellite which come from A-Train Satellite formation during the period from December 2012 to November 2016,the distribution and vertical structures were discussed and analyzed. The results show that, the occurrence frequency of ice cloud is 55.1% over the last four years and the occurrence frequency of ice cloud in spring is mostly greater than 70% apart from the Midwest area of Hexi-Inner Mongolia, it has obvious seasonal variation. The amplitude of season variation is bigger in 2015 and 2016 than the first two years, and ice cloud occurrence frequency generally small in the desert area. The high occurrence frequency of ice cloud area is in the northeastern part of the Qinghai-Tibetan Plateau because of the special terrain ; The occurrence frequency of ice cloud is both bigger in spring,autumn and winter but only smaller in summer at the northeastern of the Qinghai-Tibetan Plateau,because the warm and humid air from the Indian Ocean is blocked by the southern mountain of the plateau,which leads to a lower occurrence frequency of ice cloud in the northeastern of plateau in summer. The ice water content is almost has no ice water distribution above 13 km, ice water content in Northwest China is the biggest in summer and almost has no ice water distribution below 5 km because of the high temperature in summer that make ice cloud not easy to form in the lower floors, and the ice water content is generally smaller in autumn and winter . The difference of ice water content between different regions in northwest of China is relatively large ; Ice cloud effective radius and ice water content had a similar trend in the whole of Northwest China area and five different sections,which are bigger in spring and summer and smaller in winter and autumn ; Especially in summer,ice effective radius is generally larger,but ice cloud effective radius is relatively small in the numerical value of ice water content area 37°N 39°N because of the higher temperature in summer. The difference of the Ice cloud effective radius between different regions in Northwest China is relatively larger,the Ice cloud effective radius is minimum in The east seasonal wind areas of Northwest China and biggest in Northern Xinjiang and the midwest of Qilian Mountain-Qinghai area.
