Understanding Precipitation: Forms, Impact, and Factors

Learn about the main forms of precipitation - rain, snow, hail, and sleet, factors influencing humidity and cloud formation, and types of precipitation like ice pellets. Explore how air rises through orographic lifting, frontal wedging, convergence, and convective lifting. References and quiz included.

  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
