electrostatic forces cause clouds and dust to stick together and aggregate into a big clump and be liable to precipitate
this by itself is going to change the motion of the atmosphere, the drops and dust moving together pushes the air away
it essentially will induce a cloud front which is exactly one of the things that causes wind during storms, a sharp difference between air pressure in the cloudy, wet area and the dry, de-dustified area
if you have ever used an air ioniser and tried making an earthing mat to catch the dust, you'll see that the dust is pulled towards the earthed metal surface, because this allows it to discharge its energy
the same electrostatically driven motion will cause a big enough differential to induce air to move violently
