The precipitation is composed of ice particles in the upper altitude, snow, graupel, raindrops and the cloud liquid water in the lower altitude. 分析模拟结果中特定点的水成物垂直分布发现:降水 云由 高空冰晶、中低空雪、霰、 云水及低空雨水等组成。
Vertical distributions of cloud water, cloud graupel water and vertical velocity further approved the low level characteristics of cold airstream precipatition. 云水含量、云中霰含量和上升速度的垂直分布进一步证实了冷流降水的低空性。
