الاتجاه العام لقيم الاشعاع الشمسي و سرعة الرياح و أثرهما على التبخر في المنطقة الجنوبية من العراق

Abstract EN

This study focused on the trends of actual solar radiation reaching the surface of the earth in the southern region of Iraq during the period (1988-2017), which are related to various clouds and dust phenomena, as well as air pollutants, which lead to blocking, reversing and absorbing a large proportion of solar radiation.

The study also dealt with the wind element in terms of its speed, and then the study dealt with the effect of solar radiation trends and wind speed and measuring its effect on evaporation and evapotranspiration.

We can make possible through finding appropriate statistical relationships.

The study found that there is a decrease in the trends of actual radiation values and wind speed and in most of the stations included in the study, and the study showed a direct correlation between the directions of actual radiation and wind speed on one side and the amounts of annual evaporation and evapotranspiration on the other side during the study period.
