Extreme Rainfall over Iraq for some Cases and its Association with Atmospheric Rivers (ARs)

Heavy rainfall is closely associated with atmospheric rivers (Ars), which are long, narrow bands and ephemeral corridors with significant water vapor flux. Globally, atmospheric rivers (ARs) are the cause of a number of hydroclimatic extremes. Their mechanisms and roles in the Middle East's flooding are not well known. This paper uses a vertically integrated moisture flux transit (IVT) based model to evaluate the relationships between Ars and intense rainfall. We consider two scenarios of heavy precipitation over Iraq in 2023 and 2012. The findings indicate that Ars is responsible for all of Iraq's extreme rainfall occurrences, which occur throughout the rainy season. consequences of the primary sources of ARs in Iraq. Red Sea, north Africa, and Gulf of Aden. For those intense (Ars) traveling through the area, the red sea is an essential supply of moisture.
