Freezing drizzle is
drizzlethat freezes on contact with the ground or an object at or near the surface. Its METARcode is FZDZ. When such drops land, it creates an icy layer of glaze. Freezing drizzle alone does not generally result in significant iceaccumulations due to its light, low-intensity nature.
Drizzle is formed in low level
clouds, of the stratustype, when vertical motion is weak. It consists of relatively small drops, light in nature. Freezing drizzle generally occurs when drizzle forms in an airmass at below freezing temperatures but warmer than -10 °C (12 °F). At such a temperature, the water droplets stay supercool as there are few ice nuclei to change them to ice crystals (see freezing rain). In winter arctic conditions, it can happen at even lower surface temperatures as the air is even cleaner.
