Nota Adicional1
Precipitation includes drizzle, rain, snow, snow grains, ice crystals (diamond dust), ice pellets, hail, small hail and/or snow pellets.
Nota Adicional2
As this is usually measured in a fixed rain gauge, small amounts of dew, frost, rime, etc., may be included in the total. The more common term rainfall is also used in this total sense to include not only amounts of rain, but also the water equivalents of frozen precipitation. For obvious reasons, precipitation is the preferred general term.
Contexto
The character of precipitation can be defined as being one of three forms, namely showers, intermittent precipitation, and continuous precipitation. Showers are those precipitation events associated with physically-separated convective clouds. Observers (or instruments replacing humans) also have to classify precipitation into the three intensity categories: light, moderate, and heavy, according to the rates of precipitation fall or other related factors (such as visibility).
