Trees, rain and soil
The humidity and the clouds of the tropical zones are not the fact of the fate. It is the trees which maintain them in this state by releasing through evaporation enormous volumes of water. This vapor condenses by forming clouds, the rain falls, trees grow and their roots retain the shallow layer of ground and the mould of dead leaves where the nourishing elements are quickly recycled by bacteria.
The cycle is broken
Remove trees and rain will stop. Trees and rain are inextricable: no trees without rain and vice versa. Without rain, the ground is going to decay since the bacterian ecosystems which maintain it are exposed to hostile conditions and to erosion, and the forest will be replaced by the wilderness or the desert.
