基于CloudSat识别飞机积冰环境中的过冷水滴
Identifying the Supercooled Liquid Water in Aircraft Icing Condition Using CloudSat Satellite Data
摘要
Abstract
The statistic characteristics of 127 PIREPs (pilot reports)including icing type,cloud classifica-tion,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.2B-CWC-RO 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℃.关键词
