Question

Under what circumstances could the relative humidity exceed 100% without producing condensation in the air?

Answer 1

If you continue to cool air after it has reached the relative humidity of 100% and there is not enough condensation nuclei for the satuated water vapor to condense upon, the waer vapor will then exist in a state of super-saturation.  See the following links for more details:
