采用NASA地球观测系统(EOS)“云与地球辐射能量系统(CERES)”2002-12至2007-12的CERES SSF Aqua MODIS Edition 1B/2B/2C云资料,选取新疆阿尔泰山、天山和昆仑山三大山区,通过分析总云量的多年平均空间分布、季节变化以及年变化特征,考察了新疆山区云水资源情况。结果表明,多年平均的阿尔泰山、天山和昆仑山总云量区域平均值为43.47%、44.91%和52.72%,其云水资源有较大开发潜力。其中昆仑山的云资源最丰富,但其自然转化为降水的效率较低,可以通过人工增水提高其转化率。三大山区总云量呈明显的季节变化和年变化,变化规律各有特点。
Based on the CERES SSF Aqua MODIS Edition 1B / 2B / 2C cloud data from NASA Earth Observing System (EOS) “Cloud and Earth’s Radiated Energy Systems (CERES) ” from December 2002 to December 2007, Xinjiang Altai Mountains, Tianshan Mountains and Kunlun Mountainous areas of the three mountains, by analyzing the annual average cloud cover the spatial distribution of many years, seasonal changes and annual changes in the characteristics of the mountainous areas of Xinjiang cloud water resources. The results show that the mean annual cloud cover areas of Altai, Tianshan and Kunlun Mountains are 43.47%, 44.91% and 52.72%, respectively. The cloud water resources have great potential for development. Among them, the Kunlun Mountain has the most abundant cloud resources, but its natural conversion to precipitation is less efficient, and its conversion rate can be increased by artificial water enhancement. The total amount of cloud cover in the three major mountain areas showed obvious seasonal changes and annual changes, and their changing laws have their own characteristics.
