一个冰川化的穿孔云的观测
Observations of a glaciating hole-punch cloud
摘要：
本文介绍了用遥感方法对一个穿孔云或落斑洞进行的测量。云是由垂直指向的红外云高计、多普勒激光雷达、天空摄像机和倾斜45度的偏振雷达观测的。多普勒激光雷达和偏振雷达的观测结果表明，飞机引起的下降条纹主要由定向的厚板晶体组成，垂直多普勒速度表明，垂直混合可能是由大量的冰流入室女座底部的干燥空气中引发的。
英文摘要：
Remote-sensing measurements of a hole-punch cloud or fall-streak hole are presented. The cloud was observed with a vertically pointing infrared ceilometer, Doppler lidar, sky camera and a polarimetric radar inclined at 45 degrees. The Doppler lidar and polarimetric radar observations show that the aircraft-induced fall streak was composed primarily of oriented thick plate crystals, and the vertical Doppler velocities suggest that vertical mixing may have been triggered by the large flux of ice into the dry air at the base of the virga.
