Forms of Precipitation

By: Flavio Gutierrez

Precipitation

• Any product of condensation of atmospheric water vapour

• Main forms of Precipitation:– Rain – Snow– Hail – Sleet

Humidity

• Relative Humidity– Amount of Water Vapor

in the air

• Dew Point– Water condenses at

ground level

4 ways that causes air to rise• Orographic Lifting

– Air is forced to rise over a mountainous barrier

• Frontal Wedging– Warmer, less dense air is

forced over cooler denser air

• Convergence– Pile-up of horizontal airflow

resulting in an upward flow

• Localized Convective Lifting– Unequal surface heating

causes localized pockets of air to rise

Basis of Cloud Formation

• Adiabatic Temperature– 10°c per 1000 meters

• Adiabatic Cooling and Condensation– Occurs when air is uplifted from the surface

Types of Precipitation

• Rain– Liquid water in a form of

droplets– Most Common

• Snow– Crystalline water ice

• Hail– Big ball of ice

• Sleet– Small translucent ball of ice– Ice pellets
