The answer to this question depends on the context. There are clouds that don't necessarily produce rain and clouds that are not associated with rain.
-
Clouds that don't necessarily produce rain:
- Stratus clouds are known for being flat and uniform, sometimes producing light precipitation or drizzle but often remaining precipitation-free.
-
Clouds that are not associated with rain:
- Thunderclouds and Lightning clouds are named for their dramatic electric discharges but don't inherently mean rain. You need to select "Rain" specifically to have rainfall in these conditions, as explained in the Forza forum post.
In the context of a video game or simulation, you can often adjust settings to have a cloudy sky without rain. This is confirmed in the discussions about ARMA 3 and X-Plane.
Ultimately, "Which cloud has no rain?" is a bit of a trick question, as most clouds can hold water and potentially produce precipitation, but some are less likely to do so than others.
