WebFreezing rain develops in a similar way to sleet, except the layer of subfreezing air above the surface is shallower. Ice pellets bounce when striking the ground, whereas freezing rain does not. Ice pellets can …
Websaturation vapor pressure is lower over ice than water => ice crystals grow in favor of liquid droplets; ice crystals are very efficient condensation nuclei; most efficient in mid latitudes (temperatures low enough, but enough instability in the atmosphere) Precipitation patterns. kinds of precipitation: drizzle, rain, ice pellets, snow, hail A typical raindrop is about 2 mm in diameter, a typical cloud droplet is on the order of 0.02 mm, and a typical cloud condensation nucleus (aerosol) is on the order of 0.0001 mm or 0.1 µm or greater in diameter. The number of cloud condensation nuclei in the air can be measured at ranges between around 100 to 1000 per cm . The total mass of CCNs injected into the atmosphere has been estimated at 2×10 kg over a year's time.
