الملخص EN

This research has handled the study of dust phenomena’s and their influence on the magnitude of sun ray in Iraq .

and has emphasized and divided these dust phenomena’s in to the following categories : The dust storms , the elevated dust , and the suspended dust and their repetition annually , and monthly , he also emphasized each one phenomena and its understanding alone.

The researcher has also mentioned to study the understanding of sun ray and its annually and monthly magnitude .

Finally the researcher emphasized how these dusty phenomena’s influence magnitude of sun ray by applying ‘Person’ equation using (spss) software program .

He found that the annual relationship between dust storms and sun ray is inversely relationship and significant in both “Kirkuk” and “Nasiriya” station and that the relationship between sun ray and elevated- suspended dust is significant inversely in both “Kirkuk” – Basra station and that the relationship between the dust phenomena’s and sun ray was proportional in must stations .
