| 摘 要： | 利用温斯顿编制的美国NOAA卫星第一批45个月辐射观测资料分析图，包括吸收太阳辐射，反射率及射出长波辐射。而地-气系统辐射平衡是用公式计算的，首次对地-气系统辐射平衡理论各分量从数值上进行逐月的和年内的纬向分布特征研究。结果表明：在一年中太阳直射点随时间的推移的南北回归线之间移动。地-气系统辐射平衡，吸收太阳辐射，反射率和射出长波辐射的纬向分布，和理论说明的变化是完全一致的，这45个月正处于太阳黑子数相对少期，该期间的太阳辐射应是偏弱的。 |

| Abstract: | Based on 45-month NOAA satellite data of radiation, including the absorbed sun radiation, the albedo and outgoing long wave radiation (OLR), as well as the formula for the radiation budget, the features are revealed for the zonally and monthly averaged (total and component) radiation budget in the earth-atmospheric system. The results show that the total radiation budget, absorbed sun radiation, albedo, and OLR of the earth-atmospheric system are in agreement with the theoretical illustration entirely. The weak sun radiation is due to the less sunspot activities during these 45 months. |
| Keywords: | the radiation budget the earth-atmospheric system sun radiation long wave radiation distribution characteristics |
