摘要
在西昆仑山地区,太阳辐射是很强的,其中紫外波段尤为明显,紫外辐射的瞬时最大值达99W/m^2。同时,紫外辐射在太阳总辐射中所占比例也很大,达8.86％。本文在1989年对西昆仑山地区进行的太阳分光辐射观测的基础上,经过统计分析表明:各波段太阳辐射值与太阳直接辐射及天空散射有极好的线性关系。并以此为基础计算了太阳分光辐射的总值(月、季、年),分析了其分布特征及年变化规律。
The solar spectral radiations are observed in the west. Kunlun Mountain region during the summer of 1989. In this paper, the spectral radiation distribution, their daily and annual variations are discussed. The results are as follows:
The energy of the spectral radiation is very strong in the west Kunlun Mountain region, in which the ultraviolet radiation is particularly large also. The instantaneous maximum of the ultraviolet radiation reaches to 99W/m2, and the ratio of the ultraviolet radiation to global radiation is very large too, reaches to 8.86%. There is a lines relationship very well among the flux of every wave-band of solar radiation and the direct solar radiation, sky diffuse radiation. The correlation coefficients are exceed to 0.99. The distribution of annual radiation have relation to sunshine. The solar radiations on each wave-band in the summer (June, July, August) close to 40%.
