Your answer:  ·  Correct: D
Explanation

The 'Shamal' is a prominent local wind characterized as a strong, dry, and often dust-laden northwesterly wind prevalent in the Middle East. It is a major climatic feature of the Persian Gulf region and the Tigris-Euphrates river valleys, which correspond to ancient Mesopotamia. The Shamal occurs in both summer and winter; the summer Shamal is often linked to the thermal low-pressure systems over the Arabian Peninsula and the mechanical forcing of the Zagros Mountains [2]. These winds frequently cause significant dust storms across Iraq and the Arabian Gulf states. While other regions like West Africa experience dry winds such as the Harmattan [1], and South Asia experiences the 'Loo' [2], the Shamal is specifically geographically associated with the Mesopotamian and Arabian Gulf regions.
