I understand that the occasional planet-wide dust storms that occur on Mars are supposed to be precipitated by solar wind and they can last for some time.

What I don't understand is: that with Mars having such a thin atmosphere, what holds the dust particles up in "the air".

The only thing I can think producing this is that the dust particles and the planet could get a large electrical "charge" makeing the dust particles repel each other.

If that is the case, what would be the effect on any electrical equipment introduced to such a unipolar environment?

Its the heat (Sunlight) that holds the dust particles up... I think

The sun heating up Mars's Atmosphere and cause the air to move.

I think I read that somewhere

Mars has seasons like Earth, but because of the elliptical orbit of Mars the length of the seasons and there intensity varies. The southern summer for Mars is 40% more intense than the northern summer. When it is a particularly hot southern spring/summer great duststorms are created.

I wonder what the effect of a Greenhouse Effect will be on Mars....
