March 19, 2021 - Dust plumes over the Arabian Sea


Dust over the Arabian Sea

Wide plumes of dust hung over the Arabian Sea and the Horn of Africa in
mid-March 2021. The Moderate Resolution Spectroradiometer (MODIS) on
board NASA’s Aqua satellite acquired a true-color image on March 18.

Strong winds have been blowing across the region for more than a week,
kicking up massive amounts of dust. The heaviest storm was on March 12,
when an intense dust storm covered northern Saudi Arabia, turning the
skies red and reducing visibility as the wind knocked over street
lights and power poles. Although wind strength had diminished by March
18, large amounts of dust remained in the atmosphere.

The Arabian Peninsula and the Horn of Africa rank among the world’s
most prolific dust-producing regions. Dust activity frequently occurs
in the springtime, when gusting winds are common in the lowest layer of
the atmosphere. This instability makes the lofting of dust particles
into the air more likely.
