Aren't all rains convective? So why are there convective and non-convective rains

Cumulus clouds that produces showers and storms are convective rains, but even drizzle from a stratiform cloud is also convective in nature just that there has been a capping of cold air beneath warm moist air layer.

So all are rains convective?

Thanks

Yes you are right, 99.9% of all precipitation were likely the result of convection. That was what we usually mean when we write the term our weather discussion with the word like "convective precipitation" is 'deep and moist convective precipitation. So remember when you see just don't want to keep writing so many words in order to keep those AFD's short and sweet. So when ever you see us using the term "convective precipitation", you will know that that was really short for deep and moist convective precipitation.

Well, as you know, water evaporates all the time, naturally. If the opposite, a condensation, occurs, it must be because the air is cooled down and that is, in nearly all the cases, the result of the adiabatic effect of rising air, thus - a convection.

But the air can also cool down by contact to the ground that cools down by radiation during the night. We then get early morning radiation fog. if the cooling is intense and the air, very moist, that fog can produce a drizzle that could, theoretically, be call, rain.
