Results of analysis of hourly measured temperatures, solar radiation intensity and B – band ultraviolet radiation intensity data in Zarka Jordon taken over the entire 2002 year are presented. The analysis emphasized on establishing correlations between these three physical quantities on one hand, and searching for any systematics or cyclic effects that may be contained within measured fluctuations on the other hand. The use of fast Fourier analysis method of data, revealed the presence of four such cycles at least. These cyclic effects may be related to air pollution in the area.
