June 30, 2022 - Dust off the Namibian Coast


Streamers of dust blew southwestward from Namibia and over the Pacific Ocean in late June 2022. The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image showing nearly a dozen long tan-colored dust plumes on June 27.

The landscape of Namibia is often arid and filled with copious loose sand and dust, including the Namib Desert—one of the most arid places on Earth—which sits along the coast. Dust storms are frequent natural hazards, especially in winter, when strong winds blow down the mountains and plateaus. Called “berg winds”, these hot, dry, strong winds easily pick up dust and sand from the coastal plains and deserts and carry them far out to sea.
