Dust continued blowing over the Red Sea for the third straight day on July 16, 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture the same day. As dust plumes from Sudan blew over the Red Sea, curving toward the southeast before reaching Saudi Arabia, smaller dust plumes blew northeastward off the coast of Somalia and over the Gulf of Aden. The dust blowing from Sudan appears to arise near the coast. Clouds obscure much of Somalia, however, making it difficult to tell whether the dust blowing off that coast originated near the shore or farther inland.
This true-color image shows dust plumes blowing off the coasts of Sudan and Somalia on July 16, 2009. Both plumes head northeast, although the dust plume from Sudan changes direction to move southeast.
This true-color image shows dust plumes blowing off the Sudanese coast and over the Red Sea on July 9, 2009. The thickest dust plume blows toward the northeast, but thinner dust plumes blow toward the southeast, just missing the coast of Saudi Arabia.
