- Definição1
- A type (or form) of precipitation consisting of water droplets less than 0.5 mm (0.02 in.) in diameter and larger than 100 nm. Droplets larger than 0.5 mm are considered raindrops. Drizzle usually falls from low stratus clouds and is frequently accompanied by low visibility and fog. In weather observations, drizzle is classified as 1) light, the rate of fall being from a trace to 0.3 mm (0.01 in.) h-1; 2) moderate, the rate of fall being from 0.3 to 0.5 mm (0.01–0.02 in.) h-1; and 3) heavy, the rate of fall being greater than 0.5 mm (0.02 in.) h-1.

- Definição3
- Fairly uniform precipitation in the form of very small drops of water. The diameter of the drops is normally less than 0.5 mm. The drops appear almost to float, thus making visible even slight movements of the air. Drizzle falls from a continuous and fairly dense layer of stratiform cloud, which is usually low, sometimes touching the surface (fog). For coding purposes, drizzle must be classified as slight, moderate or heavy.

- Recent field tests (WMO, 1998) have shown that all of these systems are capable of detecting most precipitation — except for the very lightest snow or drizzle — in over 90 per cent of the occurrences.
