The Red Sea is located between North Africa and the Arabian Peninsula, the world’s largest dust source regions. Summer winds pump dust from the Sahara and Arabian deserts down a narrowing mountain-fringed passage, causing it to accumulate over the southern Red Sea. Dust suspended as aerosol particles in the atmosphere can influence climate by altering the balance between sunlight absorbed at the Earth’s surface and heat energy radiated back to space. This is known as radiative forcing.
