Does the type of clouds in the sky effect the humidity?

Question

I am wondering if the type of clouds in the sky effects the humidity. For instance, if the clouds are overcast does that mean that the humidity level is rising?

Answer 1

An excellent question. In general the answer is no. However, clouds such as cumulonimbus or towering cumulus are clouds which are growing in part due to the circulation of air near the ground and the vertical motion due to the convergence of that surface air. And there will be changes in humidity near the surface with these changes in horizontal convergence.

Answer 2

In a word, no.

But, clouds means that it is 100% humidity where the clouds are, so if there is enough moisture above the ground for there to be clouds, then it is more likely that there will be more humidity beneath them, also, than otherwise.

Now, if it rains, the humidity at "ground level" is likely to rise, too. Other than that, the clouds don't really "affect" the humidity at the surface.
