Empirical Correlations of Solar and Other Weather Parameters

Abstract

This paper presents the results of statistical analysis of extended data of nine solar and other weather parameters of the capital city area of Jordan. The regression models developed in this paper include the prediction of air temperatures, relative humidity, atmospheric pressures, daily sunshine hours, and daily solar energy incident on this area. It also includes four models developed in this research for the prediction of the clearness index of solar radiation in this area. This parameter besides its intrinsic use is needed in the prediction models of diffuse as well as direct solar radiation.
