摘　　要：从光学工程应用的角度对全国云量情况进行了研究,重点分析了全国陆地主要地区云量总体平均情况、冷暖半年、昼夜变化等三个方面云量历史数据,研究结果表明:全国陆地主要地区总云量和低云量分布区域基本呈北少南多的情况;冷暖半年云量分布有较明显的差别,暖半年云量高于冷半年的站点区域占全国较大面积;昼夜云量分布区别主要体现在西部地区白天低云低值区会有中高云存在。在云量总体平均情况、冷暖半年、昼夜变化的分析基础上进而讨论了全国云量区域的分级情况,结果表明适合光学工程应用的1级区主要分在北方。结果有助于了解全国适于开展光学工程应用的区域,并可为进一步研究云量对光学工程应用产生的定量影响提供参考。From the perspective of optical engineering application,the national cloud cover characteristics are studied,and the historical data of cloud cover in the main land areas of China in three aspects,namely,the overall average situation,the half-year change of warm and cold,and the diurnal variation,are analyzed in detail.The results show that the distribution of total cloud cover and low cloud cover in major land areas of China is basically less in the north and more in the south,and there are obvious differences in the distribution of cloud cover between the cold and warm half year,the site area where the cloud covers in the warm half year is higher than that in the cold half year is larger,and the cloud distribution difference between day and night is mainly reflected in the existence of a certaion amount of medium and high clouds in the low-value areas of low clouds during the daytime in western China.Then based on the analysis of the overall average,semi-annual and day-night variation of cloud cover,the classification of cloud cover regions in China is discussed,and it is shown that the 1 level areas suitable for optical engineering application are mainly in the north.This work is helpful to fully understand the suitable regions for optical engineering applications in whole country,and can provide support for further research on the quantitative impacts of cloud cover on optical engineering applications.
