关于帕斯奎尔稳定度类别的云量判别及入射太阳辐射量判别方法的研究

A study on the relationship between cloud amount and incoming solar radiation in Pasquill stability categories

本文给出了有云天空入射太阳辐射量计算式,将Pasquill稳定度类别的Turner(或Gordon)判别法与Smith判别法直接联系了起来。说明按有效云量即总云量与低云量之和的一半所判别的太阳辐射强度指数,将使Turner方法更简单、准确。

In this paper, the formulas calculating the incoming solar radiation through cloudy sky are given to connect Turner's (or Gordon's)approach and Smith's approach to Pasquill stability categories. It is also pointed out in the paper that the effective cloud amount defined as a half of the sum of total cloud cover and low-level cloud amount may simplify the cloud criteria and improve the accuracy in Turner's approach.
