Field studies in southeastern Morocco, just a few kilometers away from the site of this dust storm, show that electric fields generated by blowing sand boost dust emissions up to 10 times more than expected from wind alone.

Now, first - of - their - kind field tests in the western Sahara reveal that the fields — generated when windblown sand grains rub together — loft desert dust much more effectively than previously recognized, creating larger and longer lasting storms than wind alone.

Researchers conclude that the meter - scale ripples are built by Martian wind dragging sand particles the way flowing water drags sand particles on Earth — a different mechanism than how either dunes or impact ripples form.

Earth also has smaller ripples — appearing in rows typically less than a foot (less than 30 centimeters) apart — that are formed by wind - carried sand grains colliding with other sand grains along the ground.

They are fairly rare on the dry beach around here, probably because the local winds are very erratic and the sand is less sticky than ocean sand.

Once saltation is well under way, by far the majority of grains in motion are actually blasted off the sand surface by the impacts of other saltating grains, rather than being carried along directly by fluid forces of the wind.

Windblown sand grains can create electric fields that raise up to 10 times more dust than wind alone

Hot winds blowing from Africa keep Fuerteventura hotter than other resorts located at the same latitude, and can (albeit rarely) bring red sand from the desert.
