Wind?

I was wondering if you could add wind to a map... And possibly sandstorms?

sand colored clouds moving across your map terrain looks like a sandstorm... at least you can do that in hce dunno about h2v

could some1 tell me how they think you do it or how you did in in hce?

You'd just use some atmospheric fog for the sand storm clouds, and define the weather (for wind and various sand flying through air particles, etc) via a weather system tag.
