Variations in the heights of different clouds over three major mountains in Xinjiang based on CloudSat observation
As a carrier of cloud water resources,clouds play a significant role in earth water cycle and climate system.Clouds at different heights have differences in physical properties and dynamic mechanisms,which have great effect in precipitation forecast and artificial enhancing precipitation operation.ClouldSat 2B-CLDCLASS data from NASA from January 2007 to December 2008 were employed and the three ranges (Altay,Tianshan and Kunlun Mountains in Xinjiang) were selected to be the research regions in this study.Cloud water resources were determined through the analysis of height distribution of different specific type clouds.It is found that the altostratus over the three mountains occupy a great proportion in each season,over 20％.And the nimbostratus in the Tianshan and Kunlun Mountains also occupy a great proportion,over 15％.Monthly variations in cloud top height and cloud base height of different types of clouds over the three mountains are generally similar; the maximum average cloud top height and cloud base height of all types of clouds appear in the Kunlun Mountains,but in the Altay Mountains appear the minimum heights.
