Dust Blowing Around Island of Socotra12.5N 54.0E
Dust blows off the Horn of Africa (lower left) and the Arabian Peninsula (above). The Horn of Africa is a peninsula in East Africa that juts hundreds of kilometers into the Arabian Sea and lies along the southern side of the Gulf of Aden. The dust appears to originate on the Arabian Peninsula, probably in the Rub’ al Khali Desert, and blow southward. This is evident from the way the veil of dust is less thick southwest of the island of Socotra – the island partially blocks the path of the airborne dust particles as they blow in that direction.
