Title: Is constant rain possible?
Post by: Gordon Freeman on February 19, 2016, 12:00:16 PM

I had an idea for a fictional planet a couple years ago where there was so much water vapor in the atmosphere that the water cycle would go by faster than a rainstorm could finish, thus keeping it raining forever.

Is this scientifically plausible?

that sounds like Dromund Kaas

It is sort of plausible. If your planet is a water planet (mostly made of water like Kepler-22b), and relatively close to its host star (e.g. 70,000,000 km), It should create a great condition for such scenario, thought it will only happen near the equator, however (0°-40° latitude)

It certainly is possible.
For example: if you had a body of water that was constantly being heated by something that wasn't blocked by clouds or night, you'd have constant evaporation. Water vapor would rise and cool at high altitudes, then rain.
Two things come to mind that could do this: geothermal energy--maybe from a newly formed planet, or from vigorous tidal stress, or being tidally locked to some radio-bright object
