Hello, it's more about how Enviro is treating these values. You are just setting parameters in the weather profile in the Atavism Standalone Editor and they are handed over to the Enviro, but they can be sent to any other system that supports World API by Procedural Worlds, like Weather Maker, and every system can treat these data a bit differently.
This is also the reason why there are no limitations in the weather profile settings, because we don't know what system you will use and how they are treating data.
Also, not every parameter is handled by the weather system, we are exposing all that are handled by World API, so no matter which weather system you will use, you could adjust parameters as you want. Maybe Enviro documentation will help you a bit.
