I think there asking for a formula to create fractal clouds, using random values.
I would suggest checking out a fractal web site for different formulas and pick which one works best for you.
Just do a search in Google for "Fractal Clouds" and you could spend all day looking at examples.
This approach can be used for landscapes and height maps too.
