Is that coloration sand that is spread/blown laterally or vertically? Looks almost like a vertical cloud.

The lines do exist, but I'm surprised they don't get covered up by all that sand in the air.

I think you might be right. I just visited this site and the lines were not in any of the pictures. I hope your right because it would take a ton of paint to keep the lines maintained.

" The Canary Islands are the only inhabited area affected."

This iron rich dust will make it's way all the way to Florida in a few days where it will cover everything in orange. Also, when it lands in the Gulf Of Mexico, the iron causes an explosive growth of plankton (Red Tide) that causes low oxygen zones and kills fish.

Laterally. The apparent "verticality" is just an optical illusion.

Amending my last post: What's even more striking is how much the sandstorm, and some of the geographic features, look like artificial brushstrokes, as if portions of this photo were painted on.

Both, actually. The vertical motion of the storm lifts the sand vertically, and the winds advect the sand laterally.

A picture at:

has some arrows to point out the sand.

I think those are windrows of sand, deposited from all the sandstorms like this one that sweep the area. Very interesting photo.

Thanks. That's what I thought too. But when I first looked at it, my mind just read 'vertical' and I couldn't see it any other way after that. Plus I slept through those required six semesters of 'Analyzing Satellite Imagery of Saharan Sand Storms' so I was probably heading into this conundrum with a disadvantage ;-)

The problem isn't the straight lines in the sand.

(Heck, "anybody" can paint straight lines .....)

The problem is getting those neat little zig-zags on the angled lines exactly right.

[Is that coloration sand that is spread/blown laterally or vertically? Looks almost like a vertical cloud.]

Both, actually. The vertical motion of the storm lifts the sand vertically, and the winds advect the sand laterally.

Yes, the sand is of course lifted off the ground, but the amount would not be visible in this photo. Even if it were lifted up into the air as high as the top of Mount Everest, the vertical component would only be equal to five pixels of this image (less than 1% of its width).

It's easy to overestimate the "thickness" of the Earth's atmosphere, or geographic "roughness". If the Earth were the size of a billiard ball, it would be about as smooth *as* a billiard ball, even taking into account such "imperfections" as the depth of the Marianas Trench and the height of Everest. At billiard-ball size, the difference in heights of those features would amount to imperfections no greater than a few one-thousandths of an inch.

That sand is blowing in the direction of the north atlantic, towards the canary islands. I wonder how come so much of it is winding up over central Europe.

I don't have enough background in remote sensing to assess the pixel by pixel attributes of the vertical mixing versus horizontal diffusion and/or advection of the sand in the image.

Just wanted to clarify that the physical process responsible was doing both.

By the way, your analogy of the thickness of the atmosphere (and significant orographic features) comes as a new way of explaining it to me and I like it. I was used to the old standby of a dime on a common globe, but hadn't heard it from a pool ball perspective...

"I blame Global Warming."

Couldn't be ... the Mars(ians) are falling all over themselves to prove water once existed on Mars, but is long gone now. The temperature at Mars is like eleventeen gazillion degrees below zero, therefore, any evolutionary activity Mars experienced is yet on going with the universe (of which we are part) and thus proves global cooling ... not warming.

Methinks the Mars alchemists had better tread carefully to keep from upsetting the evolutionists.
