Ambient humidity vs. RH

#1
Hi all. First time on the thread. I'm involved in the timber flooring industry down here in Australia (pronounced: Oz-stray-ya), where our standards are yet to catch up to the US. Subsequently, RH moisture testing is a very under-utilized practice at the moment. I look forward to joining the discussions here.

Question, and apologies if it has been asked a million times: I note the instructional video on temperatures having little effect on the RH of the slab. What about the ambient humidity of the area?

A major adhesives manufacturer rep mentioned to me that the highest number of moisture-related flooring failures occurred in a state which is known for its hot, dry climate. This is particularly telling as this area is a much smaller market than the eastern states, with areas known for their higher humidity.

Pardon my ignorance, does this imply that the inherent slab moisture (roughly the same in all locations, give or take differing mixing techniques between concrete layers) will translate to greater RH at the floor covering area, when exposed to a drier hot climate, as opposed to a more humid environment?

Or should it mean that the RH of the slab in a drier, hotter area will decrease more quickly?
