That part of atmospheric moisture that falls on the earth surface
Precipitation
10 Types of Precipitation
- Freezing Rain
- Freezing Fog
- Snow
- Snow Grains
- Sleet
- Graupel
- Rain
- Ice Crystals
- Drizzle
- Hail
Water droplets in clouds are formed by nucleation of vapor on aerosols, then go through many condensation evaporation cycles as they circulate
in the cloud, until they aggregate into large enough drops to fall through the cloud base.
Sublimation Nuclei
a process of artificially nucleating clouds to induce precipitation.
Cloud Seeding
is a common nucleating agent and is spread from aircraft in which a silver iodide solution is evaporated with a propane flame to produce particles.
Silver Iodide
fusion or coalescence of water droplets as a result of their coming in contact through the action on them of air movement and gravitational pull.
Coalescence
are known to co-exist in the atmosphere at sub-freezing temperatures.
Ice crystals and Water droplets
4 Types of Precipitation
- Convective
- Frontal
- Orographic
- Cyclonic
the simplest method of determining areal average rainfall which involves averaging the rainfall depths recorded at a number of gages.
Arithmetic Average
