As for its administrative boundaries, the district of Samarra in the center of Salah al-Din is bordered on the north by the district of Tikrit, on the east by the district of al-Dawr and the district of Dhuluiyah, and on the south by the district of Balad and the district of Ishaki. This geographical and astronomical location gave Samarra's judiciary the characteristic of climate extremes, continental location and distance from Marine influences, as observed in space visuals (1). The research concluded that recent years have seen a continuous increase in dust storms. Tracking the climate characteristics of the study period (1990-2020) has seen a serious increase in the frequency of this phenomenon, which is caused by natural and human factors that have contributed to its increase in the Samarra district.
