GEOG-120 Lecture Notes - Lecture 16: Dew Point, Humidity, Water Vapor
Document Summary
Hydrosphere all water at or near the earth"s surface. About 75% of energy (as heat) in global atmosphere is transferred through the evaporation of water from earth"s surface. Heat energy breaks down hydrogen bonds of water. 90% from earth"s water bodies and 10% from plant transpiration. Absolute humidity a total mass of water vapor in a given volume of air. Relative humidity max amount of water vapor that can hold compared to its. Rh as the morning progresses, a warming atmosphere promotes a vapor phase. Water vapor changed into liquid upon contact with a surface. Condensation nuclei- particulate matter to which moisture can adhere. Condensation occurs when air is cooled to its dew point temperature which is the. Liquid, solid temperature to which air must be cooled to reach saturation after which condensation can occur. An indicator of the amount of moisture in the air.
