The emerging contribution of Tigris Euphrates basin dust emissions to extreme dust activity over the Arabian Peninsula.

ABSTRACT: The Arabian Peninsula (AP) is an epicenter of global dust activity, shaped by both local emissions and long-range transport. Recent observational studies suggest that the Tigris-Euphrates river basin (TE) is the dominant contributor to the intense dust periods over the AP. This study, for the first time, quantifies the influence of TE during these periods using a regionally tuned Weather Research and Forecasting model coupled with chemistry (WRF-Chem). Two simulations were conducted with WRF-Chem for three extreme dust seasons (March-August; 2009, 2011, and 2012): one with dust emissions from all sources, including TE, and the other with TE emissions excluded. Results show that excluding TE emissions significantly reduces mean atmospheric dust loading and decreases dust concentrations acro
