摘要
本文分析了两种观测仪器的在不同月份、季节、天气条件下的差异分布特征,得出以下结论。(1)直接辐射表采集的数据高于人工观测的日照数据。两种观测日照时数日值除6月、7月、8月外,其他月均存在显著差异,且差异呈明显的季节变化规律,在夏季差异最小,秋季次之,冬季和春季较大。(2)受仪器和天气的影响,在晴空、多云天气条件下,直接辐射表较人工日照计观测记录偏高;在阴天条件下,直接辐射表较人工日照计观测记录平均偏低。
In this paper, the characteristics of the different distributions of the two instruments in different months, seasons and weather conditions were analyzed, and the following conclusions were drawn. First, the data collected from the direct radiation meter are higher than the observed sunshine data. Except for June, July and August, there were significant differences in the daily values of sunshine hours between the two kinds of observation, and the differences showed obvious seasonal variation regularity. The difference was the smallest in summer, followed by autumn, and greater in winter and spring. Second, influenced by instruments and weather, in clear and cloudy weather conditions, the direct radiometer was higher than the artificial sunlight observation record; in cloudy weather conditions, the direct radiometer was lower than the artificial sunlight observation record on average.
