Weather Tidbits: Saharan Dust & Tropical Development
This Weather Tidbits explains how Saharan Dust plays a role on tropical cyclones. Saharan dust is dust from the Saharan Desert; that is picked up by winds and carried through the tropics. A tropical cyclone forms by abundant moisture and water temperatures above 80°. Saharan dust while traveling in the tropics, brings with it drier air. Also, the dust causes some sunlight to be reflected which means less sunlight; which results in cooler water temperatures that limit the chance of tropical development.
