The second large plume of Saharan dust reached the Caribbean and South America on June 7, 2022, after a journey of more than 5 500 km (3 400 miles), as forecasted by Copernicus CAMS and confirmed by Sentinel-5p Aerosol index.
This mass of very dry, dusty air is called the Saharan Air Layer (SAL). It typically ramps in mid-June and subsides after mid-August.
The Saharan Air Layer has unique properties of warmth, dry air, and strong winds that can have significant moderating impacts on tropical cyclone formation and intensification.
