- Nota adicional2
- 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.
- Contexto
- 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.
- Supercooled water droplets or precipitation, used only with FG, DZ, RA and UP (automatic systems only).
