摘要:

通过对2010 ~ 2011 年河北省地面紫外辐射和太阳总辐射的观测资料进行统计分析,表明紫外辐射和太阳总辐射相关显著,相关系数可达0. 99( P < 0. 001) 。紫外辐射夏季最大,冬季最小,一日中14 时左右达到最大值; 在空间上,呈南少北多纬向分布特征。云量和空气污染物对紫外辐射具有显著削减作用。

关键词: 紫外辐射, 太阳总辐射, 时空分布

Abstract:

The observational data of surface ultraviolet radiation and global solar radiation from 2010 to 2011 in Hebei had been analyzed.Results showed that the correlation between ultraviolet radiation and global solar radiation was well,and the correlation coefficient was up to 0. 99( P < 0. 001) . The maximum of ultraviolet radiation was in summer and the minimum was in winter,and the maximum UV radiation in a day was around 14: 00. The UV radiation was less in south part and more in north part of Hebei Province. By the analysis of the relationship between ultraviolet radiation and cloud mount as well as air pollutants,we found that they reduced the
ultraviolet radiation significantly.

Key words: ultraviolet radiation, global solar radiation, spatial and temporal distribution
