| 摘 要： | 该文利用2018年1月—12月成都东北部地区的太阳辐射观测资料,分析了辐射能量的收支状况和特征。结果表明:成都东北部地区各辐射分量(除净长波辐射)均是夏季最强,冬季最弱,最大值出现在8月。净长波辐射春季最强,秋季最弱,与空气相对湿度、气温日较差分别成负相关、正相关。净全辐射白天为正值,晚上为负值。成都东北部地区全年有10.7%的太阳短波辐射被地表反射,接收的太阳短波辐射有29.36%被地表以长波辐射的方式释放到大气,对地气系统能量收支的贡献为61.18%。

| Abstract: | Based on the solar radiation observation data in northeastern Chengdu from January to December 2018, this paper analyses the status and characteristics of radiation energy budget. The results show that the radiation components (except net long-wave radiation) in northeastern Chengdu are the strongest in summer, the weakest in winter, and the maximum occurs in August. The net long wave radiation is the strongest in spring and the weakest in autumn. It is negatively and positively correlated with relative humidity and diurnal temperature difference, respectively. Net total radiation is positive in the daytime and negative in the evening. In the northeast of Chengdu, 10.7% of the solar short-wave radiation is reflected by the surface. 29.36% of the received solar short-wave radiation is released to the atmosphere by long-wave radiation, which contributes 61.18% to the energy budget of the earth-atmosphere system. |
