How is it possible for it to rain at night?

788 views

I know it seems like an odd question but i’ve never found an answer. (or maybe just never fully understood the water cycle.)

This is what confuses me.

If evaporation occurs from the sun, and clouds begin to drop rain when they are “full,” How is it possible for it to rain in the middle of the night?
If a cloud is already full, why does it not rain til at night?
If its not full, then how is water being evaporated into the cloud at night?

One thing this discussion has been lacking so far is *inertia*.

The largest-scale weather systems are the product of days (even weeks) of heating, energy collection, and dissipation. Even smaller-scale features like pulse thunderstorms have a life cycle of an hour or so to even longer for more involved systems.

It may be night where you are, but it’s daytime somewhere else. All over the world features are [being generated and dissipated](https://weather.cod.edu/satrad/?parms=global-fulldiskeast-airmass-24-0-100-1&checked=map&colorbar=undefined); they just may happen to pass over you at nighttime.
