Abstract:
The statistic characteristics of 127 PIREPs (pilot reports) including icing type, cloud classification, temperature and supercooled liquid water content are investigated based on the CloudSat data. The results indicate that most of the aircraft icing events happened in the environment with temperature above -20℃, only four appeared below -20℃. Clear ice mainly occurs between -5~0℃, rime ice between -20~-10℃, and mixed ice between -15~-5℃. Most aircraft icing happens in the stratocumulus (Sc), altostratus (As), and nimbostratus (Ns). The supercooled liquid water content and its distribution decrease with decreasing temperature. 2BCWCRO product can identify the supercooled liquid water in the Sc, As and Ns, but it can’t identify the supercooled liquid water in cirriform cloud and convective cloud when temperature is below -20℃.
