Bergeron Process

Ice crystal process that needs water vapor, ice crystals, super cooled water drops in equillibrium with the vapor.

Cloud Seeding

A form of weather modification that attempts to change the amount or type of precipitation that falls from the clouds

Cloud Seeding Process

Disperses substances into the air that serve as CCN or IN

Snow

Precipitation composed of white or translucent ice crystals, chiefly in complex branched hexagonal form and often agglomrated into snowflake

Snow Squall

A sudden wind associated with snowfall that occurs suddenly and is usually intense and short lived

Graupel/Snow Pellets

crystals or frozened drops that grow through accretion of super cooled liquid water

Freezing Rain

Precipiation that falls to the ground as a liquid and then freezes upon impact with the ground or exposed objects. Forms a glaze of ice

Hail

Hail grows from accretion- freezing of super cooled liquid water droplets upon collision with particles of ice. they grow as they fall

Mesoscale

thunderstorms

large scale

extra tropical cyclones

small scale

tornadoes

Rising motion may be brought about by

free convection, forced lifting, and upper level lifting

Cumulus State

cumulous clouds can grow both vertically and horizontally (if conditions are favorable). These thermals rise and cool at the dry adiabatic

Entrainment

The process by which saturated air from the growing cumulus cloud mixes with the surrounding cooler and drier unsaturated air
