Abstract

This study examines the impact of low-level vertically integrated moisture flux (IVT) features on precipitation in Iraq and surrounding areas during the rainy season. The study calculates and analyzes the IVT across the region. It identifies the maximum precipitation linked with IVT from January to December (1981-2020). In addition, it determines the IVT threshold for each month using wind component data (u, v) and specific humidity data. The findings reveal that IVT has a greater impact in dry and semi-arid areas, the Mediterranean Sea and the Red Sea are the main sources of IVT. The Red Sea has an impact on Iraqs south and south-central region while the Mediterranean Sea has an impact on Iraqs north and north- central region. The study also finds a strong correlation between IVT and precipitation over Iraq during the rainy season with the amount of precipitation largely influenced by the intensity and direction of IVT. The results suggest that IVT transfer from the Mediterranean and Red Seas has a significant impact on the amount of precipitation over Iraq and the neighboring areas.
