Didn't Spirit or Opportunity have an anemometer strapped to them somewhere, so we could get an idea of real wind speeds, rather than computer simulations?
A new geophysical study of Mars' sand dunes has claimed that the Red Planet may be a windy place after all, despite the evidence of previous experiments. The shifting red sands of the planet have up till now been attributed to carbon dioxide ice sublimation, since boffins believed that strong winds weren't a possibility in the …
A child's windmill in sight of the camera would've done the trick
Apparently not (might have been too much weight), though "Curiosity" will be carrying a weather station with it.
No spice nearby, though...
M'ars is quite blustery and at times very blustery indeed.
There seem to be strong associations between dietary input and gaseous output at empirical/observation levels and a whole lot of research identifying, qualifying and quantifying these associations seems critically important.

A piece of string
A piece of string tied to a vertical mast on a rover and we'd have the answer.
As seen from Earth!
Mars is a planet well known for having occasional planet-wide sandstorms. I think one of those would qualify as "quite blustery" ... as well as being quite able to move the odd sand dune.
Why didn't they ask you?
That's what I thought too. Sandstorms without wind is a novel concept.
What makes you think it is sand?
I was under the impression that there were *dust* storms. A few billion years of a gentle breeze plus a little bit of freeze-thaw action should generate dust particles so fine that even a fairly insubstantial wind could keep them aloft.
The Spirit and Opportunity Mars rovers got caught in a months-long dust storm, and the major issue was the solar panels getting a bit dirty. Clearly the mass of material being shifted by the storm was pretty small.
already captured on camera!
Those two plucky little rovers have already taken photos of dust-devils scooting along.
