Dust Storm across the Red Sea • Earth.com dust storm across red sea

Dust Storm across the Red Sea leaves a thick snake of tan dust slithers across Egypt, Saudi Arabia, and the Red Sea.

The dust is so thick that it is completely opaque for well over 700 miles across its south-moving front, from the border of Iraq, across the Arabian Desert of Saudi Arabia and Egypt, and all the way past the green ribbon of the Nile to the Libyan Desert in western Egypt.

While the top true-color image is impressive in its own right, the underlying Land Surface Temperature image is striking .

Also while the bare deserts are an incandescent hot red, the dust snake is a cool blue, with a warming green and yellow halo.

Because the dust is suspended in a cool air system, its temperature falls to match that of the air around it.
