摘要:

利用呼伦贝尔沙地鄂温克自治旗2019年观测的辐射资料,对该地区的紫外辐射和总辐射进行了初步分析。结果表明:紫外辐射、总辐射年变化位相基本相同,年曝辐量分别为240.33、5 142.41 MJ·m-2,年均日曝辐量分别为0.66、14.09 MJ·m-2,紫外辐射年均日曝辐量小于西藏拉萨地区;紫外辐射辐照度和总辐射辐照度最大值出现在6月,分别为50.09、1 075 W·m-2,最小值出现在12月;紫外辐射和总辐射皆表现为夏季>春季>秋季>冬季;沙尘暴对太阳辐射的减弱作用最明显,分别对紫外辐射和总辐射削减78.46%和76.19%,降雨减弱作用较小;紫外辐射日均曝辐量在总辐射中所占比例集中在3.42%—4.95%,年均值为4.64%,大于塔克拉玛干沙漠肖塘地区。

Abstract:

Based on the data of solar radiation from Ewenke autonomous area of Hulun Buir Sandy Land in 2019, the characteristics of ultraviolet (UV) radiation and global radiation were analyzed. The results showed that the annual variation phases of UV radiation and global radiation were same, basically. The annual total values of UV radiation and global radiation were 240.33 MJ·m-2 and 5 142.41 MJ·m-2, and daily total values of UV radiation and global radiation were 0.66 MJ·m-2 and 14.09 MJ·m-2, respectively. The total value of UV radiation was less than that in Lhasa. The maximum instantaneous UV radiation (50.09 W·m-2) and global radiation (1 075 W·m-2) emerged in June, and the minimum instantaneous of that emerged in December. The order of UV radiation and global radiation was summer>spring>autumn>winter. The results showed that sandstorm had the most obvious weakening effect on solar radiation, which reduced UV radiation and global radiation by 78.46% and 76.19%, respectively, and rainfall had little weakening effect. The proportion of daily average UV radiation exposure in global radiation was mainly concentrated in 3.42%-4.95%, with an average annual value of 4.64%, which was larger than that in Xiaotang area of Taklimakan Desert.

Key words: UV radiation, global radiation, Hulun Buir Sandy Land
