on the windward side of the mountain, should the relative humidity of the parcel change as it rises from 3000 feet to 6000 feet? Why?

Answer 1

Yes, the relative humidity of the parcel should change as it rises from 3000 feet to 6000 feet on the windward side of the mountain. This is because as the parcel rises, it will cool adiabatically, which will cause the air to become more saturated and the relative humidity to increase.
