%X 全球气候变化正逐渐威胁到人类的生存环境及社会经济的可持续发展。云作为调节气候的重要因素之一，是气温及降水等气象因子发生变化的主要原因，其形成与变化对调节地球气候起着重要作用。其中，云特性变化可能对气候产生重大影响，反之，气候变化也会引起云特性的调整。本文利用Himawari-8云产品数据分析了2015年7月~2020年6月内蒙古地区的云特性参量，包括不同类型云的云量、云光学厚度和云有效粒子半径等时空变化特征，因此得出以下主要结论。内蒙古地区总云中高云所占比例相对较大，在年平均总云云量、云光学厚度和云有效离子半径之中高云的贡献率分别达到38.09%、51.46%、63.02%。在年尺度上，总云主要分布在内蒙古东部和中部地区，呈现出云参量从东北向西南减少的特征；高云主要分布在内蒙古东部、北部和中部地区。在季节尺度上，总云和高云的云量、云光学厚度和云有效粒子半径夏季达到最大值，夏季总云云量的平均值达到63%，总云光学厚度的平均值达到9.44，总云有效离子半径的平均值达到9.37 μm。夏季总云与高云的云量主要分布在内蒙古中、东部地区，夏季总云与高云的云量呈增加趋势的区域主要分布在内蒙古西部地区，冬季总云和高云的云光学厚度和云有效离子半径值相对较少，主要分布在内蒙古东北部地区。
Global climate change is gradually threatening the living environment of human beings and the sustainable development of the social economy. As one of the important factors regulating climate, the cloud is the main reason for the change of meteorological factors such as temperature and precipitation, and its formation and change play an important role in regulating the earth’s climate. Among them, the change in cloud characteristics may have a significant impact on the climate, and conversely, climate change will also cause the adjustment of cloud characteristics. In this paper, the Himawari-8 cloud product data is used to analyze the cloud characteristic parameters in Inner Mongolia from July 2015 to June 2020, including the temporal and spatial variation characteristics of cloud amount, cloud optical thickness and cloud effective particle radius of different cloud types, so the following main conclusions are drawn. The proportion of high clouds in the total cloud in Inner Mongolia is relatively large, and the contribution rates of high clouds in the annual average total cloud quantity, cloud optical thickness and cloud effective ion radius reach 38.09%, 51.46% and 63.02%, respectively. At the annual scale, the total clouds are mainly distributed in the eastern and central regions of Inner Mongolia, and the cloud parameters decrease from northeast to southwest. High clouds are mainly distributed in the eastern, northern and central parts of Inner Mongolia. On the seasonal scale, the cloud cover, cloud optical thickness and cloud effective particle radius of total and high clouds reached the maximum values in summer, and the mean of total cloud cloud amount reached 63%, the mean of total cloud optical thickness reached 9.44, and the mean of total cloud effective ion radius reached 9.37 μm in summer. The cloudiness of summer total clouds and high clouds were mainly distributed
