| Abstract | ||
| This study examined the seasonal and annual distributions of precipitation and sulfate aerosols over the Blue Nile region between 2003 and 2020. Aerosols are tiny solid or liquid particles suspended in the atmosphere. In addition to examining the relationship between precipitation and sulfate aerosols which are created when sulfur dioxide reacts with water vapor and other gases in the atmosphere. Analysis indicated that sulfate aerosol concentrations are markedly elevated during the summer season and attain their nadir in winter. Significantly, the peak precipitation levels occur during the northern summer season, which aligns with the southern winter, coinciding with the period of greatest sulfate concentration. A similar positive association was seen between precipitation levels and sulfate aerosol concentrations at all monitoring stations in the region over the study period from 2003 to 2020. This raises the possibility of a connection between increased sulfate aerosols and more precipitation throughout the summer months in the Blue Nile. | ||
