摘要: 作为空中水资源的重要组成部分,云在地球水循环过程和气候系统中扮演着重要角色,不同高度的云因其物理特性和动力过程的不同而对人工增水作业具有不同的指示意义. 采用2007年1月至2008年12月的美国宇航局(NASA)云卫星(CloudSat) 2B-CLDCLASS资料,从不同类型云的高度分布特征分析了新疆阿尔泰山、天山和昆仑山区的云水资源情况.结果表明:各个季节三大山区高层云所占比例均较大,在20%以上,其中,天山山区和昆仑山区雨层云所占比例也较大,在15%以上. 三大山区不同云的云顶和云底高度年变化趋势基本一致,昆仑山区各类型云的平均云顶和云底的高度最大,阿尔泰山区的最低.

关键词: 云水资源, CloudSat, 云顶高度, 云底高度, 新疆

Abstract: 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.

Key words: cloud water resources, CloudSat, cloud top height, cloud base height, Xinjang
