Humidity Relative Humidity – Amount of Water Vapor in the air Dew Point – Water condenses at ground level Upload.wikimedia.org

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 geogrify.net

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
