1. Forms of Precipitation By: Flavio Gutierrez

2. Precipitation Any product of condensation of atmospheric water vapour Main forms of Precipitation: – Rain – Snow – Hail – Sleet

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

4. 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

5. Basis of Cloud Formation Adiabatic Temperature – 10 °c per 1000 meters Adiabatic Cooling and Condensation – Occurs when air is uplifted from the surface

6. 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 www.easttennesseewildflowers.com
