| 摘 要： | 采用CloudSat卫星资料2B-CLDCLASS及2B-CWC-RVOD数据集和Aqua卫星资料的CERES Aqua MODIS Edition 3A数据集,针对2010年12月2-4日北疆地区一次暴雪过程分析了云的类型分布、冰粒子等效半径、低层云等效高度等宏微观物理属性的垂直分布及空间分布情况。结果表明,此次暴雪过程中,云层分布在12km以下,云中冰粒子等效半径和冰水含量均随云层高度增加而减少,冰粒子数浓度在垂直高度上呈单峰分布,高值分布在云层中部5.5km处。北疆地区暴雪前和暴雪后基本为低层云云量小于40%的低值区,暴雪时则为大于60%的高值区,云等效高度暴雪前和暴雪后大多为小于6km值域区,暴雪时为大于6km的高值区。

| Abstract: | Using CloudSat satellite data sets of 2B-CLDCLASS and 2B-CWC-RVOD and CERES Aqua MODIS Edition 3A data sets the cloud types, the vertical distribution of cloud microphysical properties such as ice effective radius, ice water content and ice number concentration and the spatial distribution of cloud macro-physical properties such as cloud amount and mean cloud effective height for low layer cloud in a snowstorm of Northern Xinjiang were analyzed in 2010 December 2-4. The results showed that, during the snowstorm, the clouds were distributed below 12km, and ice effective radius and ice water content were increased along with the cloud height increasing. The ice number concentration showed a unimodal distribution in vertical height, and the high values of ice number concentration were distributed in the clouds at the central which were in 5.5km. The values of cloud amount for low layer cloud were less than 40% before and after the snowstorm while those were greater than 60% in the snowstorm. The values of mean cloud effective height for low layer cloud were less than 6km before and after the snowstorm while those were greater than 6km in the snowstorm. |
