Question

In general, what conditions creates a drizzle or light rain?

Answer 1

Give me a minute.

Answer 2

Drizzle is normally produced by low stratiform clouds and stratocumulus clouds.

Answer 3

To produce drizzle or light continuous rain, the cloud must be rising but very slowly. This is because precipitation only occurs when a saturated air mass cools down and condense more droplets that reach the size needed to precipitate. Or else, clouds simply evaporate!

From that we conclude that it must be an air mass only slightly unstable, i.e. colder air above warmer one, but not of a great difference. This will be seen e.g. slightly ahead of an advancing warm front. The clouds will then often be called nimbostratus. It has perhaps the same dark look from under as a cumulonimbus but it is not a cauliflower-like topped cloud as those of the cumulus family, and therefore is called a nimbo-stratus, where nimbus means rain and stratus means, layer.
