Re: SAL Outbreak

Look at the bottom of the image where it says Saharan Air Layer Tracking Product. Great easterly winds (surface and aloft) sweep vast quantities of dust-filled dry air off the west coast of equatorial Africa. This air layer chokes off any convective activity and suppresses the development of tropical waves in the eastern Atlantic. At times, an outbreak can be so significant that African dust makes it westward all the way to the Pacific Ocean.
