摘要
本文着重讨论计算太阳总辐射的起始数据和经验系数的稳定性问题。在作者已完成晴天太阳总辐射计算的基础上,对实际云天条件下的总辐射进行拟合,并将其与其他方法结果进行比较。同时,还对各类公式的敏感性和经验系数的稳定性进行检验。结果表明,本文所得公式精度较高,系数较稳定,总辐射对该式系数变化的反应并不敏感。还分析了经验系数的地理分布。发现经验系数与年平均水汽压的负相关比较明显。最后简单地分析了总辐射的全国分布。
Emphasis is laid on the stability of the initial data and empirical coefficients forcalculating the global solar radiation (GSR) in this paper. Using the GSR from clearskies as the initial data for calculating the GSR is an effective method if it can be com-puted in advance. The formula for computing the GSR under actual weather conditions isremade on the basis of the work completed by the authors and the results are comparedwith others. Meanwhile,both the stability of the empirical coefficients in different kindsof formulas and the sensitivity of these coefficients to the GSR are examined. Resultsshow that the formula used in this paper has high accuracy,stable coefficients and lowsensitivity compared with others. The geographical distribution of the coefficients is an-alyzed and the coefficients at the non-actinological stations are worked out via interpo-lation. As a result, the GSR over China is computed.
