| Abstract | ||
| This work presents the results of statistical analysis of observed and severe dust visibility in Iraq in relation to the sunspot cycle for the periods 1959-2007 for Baghdad, 1978-2001 for Rutbah and 1987-2007 for Mousl, Nasiriyah and Basrah. Examination of each dust series was subjected to time and spectral analysis based on lag correlation. The result shows presence of a significant dust cycle similar to the sunspot cycle. The cross-correlation between the dust and air temperature with the sunspot activity shows a high correlation with the 11year sunspot cycle. Moreover, Fast Fourier Transformation spectral analysis for the dust series confirms the similarity agreement to the sunspot variations. | ||
