Drizzle
From Wikipedia, the free encyclopedia
- For other uses of Drizzle see: Drizzle (disambiguation).
Drizzle is fairly steady, light precipitation. The drop size of drizzle is smaller than that of rain, averaging 0.5 mm in diameter. Though drizzle may be produced by low cumuliform clouds, it is more commonly associated with stratiform clouds.
Freezing drizzle occurs when supercooled drops land on a surface whose temperature is below freezing. This phenomenon can occur at very low temperatures -- Yellowknife had several hours of freezing drizzle on January 31, 1997 while the temperature remained near -18oC (0oF).
