Abstract：Based on CloudSat data from December 1,2007 to November 30,2008,an algorithm for identifying aircraft icing potential associated with subcooled liquid water in the cloud is built.The algorithm is used to statistically analyze the global frequency of aircraft icing potential in the year,and to provide some references for aviation safety,especially for long-distance flights.The distribution characteristics of aircraft icing potentials in different cloud types and seasons are also analyzed.The results are shown as follows.There are latitudinal,sea-land and seasonal differences in aircraft icing potentials around the world.For different latitudes,mid-and high-latitudes are of high-frequency areas,low-latitude areas,especially in the areas near the Tropics of Cancer and Capricorn,are the low-frequency areas;for different cloud types,the potentials of ice accretion in the middle and high latitudes are mainly stratus,stratocumulus,altostratus and altocumulus while in low latitudes,it is dominated by deep convective clouds;for different seasons,the icing frequency is low in summer and is relatively high in winter and spring.
