青藏高原地区总辐射超太阳常数的观测研究

为了研究青藏高原地区 (以拉萨站为代表 )太阳总辐射的变化情况 ,分别使用常规观测站资料和自动观测站资料。常规观测资料使用的是逐日太阳最大总辐射以及出现太阳最大总辐射的时刻。 1993年开始实施的中日亚洲季风研究计划 ,太阳总辐射是每隔 2 0 min采集一次。基于上述资料研究发现有青藏高原太阳总辐射大于太阳常数的反常现象。并对这种反常现象进行了统计 ,得到了一些有意义的结果 ,最后在非局域力学平衡 (NLTE)假设下 ,对出现这种现象提出了可能的解释。

Observational study of super solar constant of the solar radiation over Qinghai-Tibet Plateau

To study the change of the solar radiation in Qinghai Tibet Plateau the data of the conventional and automatic observational stations are used. The conventional observation data include the maximum daily solar radiation and the time occurred. The Sino Japan Asian Monsoon Project since 1993 has collected these data every 20 minutes. The anomaly of the solar radiation greater than the solar constant in Qinghai Tibet Plateau is discovered based on the study of the above data. The statistics of this phenomenon shows some interesting results. Under the hypothesis of non local thermodynamic equilibrium the possible explanation for this phenomenon is presented.
