PPT-Humidity & Precipitation

Water Vapour in Atmosphere Amount of water vapour in atmosphere humidity is measured by an instrument called hygrometer Significance of Atmospheric Moisture Water vapour absorbs . Chapters 4 and 5. 1. Class #3 July 9, 2010. Atmospheric Humidity. Chapter 4. 2. Class #3 July 9, 2010. Circulation of Water in the Atmosphere. A general definition of humidity is the amount of water vapor in the air.. Cloud Naming. Prefix indicates height. Cirro. .  high, 5-13 km. Alto  middle, 2-5 km. (none)  low, 0-2 km. Name for appearance. Cirrus .  wispy strands. Stratus  layered, uniform. Cumulus puffy with vertical structure. ABSOLUTE HUMIDITY:. Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature. The higher the amount (weight) of water vapor per kilogram, the higher the absolute humidity. . Precipitation. We’ve studied the water cycle, and last week we focused on the “Condensation”. part. Now, we are going to discuss the precipitation part of the water cycle.. Let’s watch this video on Precipitation!. Learning objectives.
