Water Vapor Feedback
qMixing Ratio = the dimensionless ratio of the mass of water vapor to the mass of dry air.
qSaturated Mixing Ratio tells you the maximum amount of water vapor an air parcel can carry.
qThe saturated mixing ratio is a function of air temperature: the warmer the temperature the larger the saturated mixing ration.
q     è a warmer atmosphere can carry more water vapor
q     è stronger greenhouse effect
q     è amplify the initial warming
q     è one of the most powerful positive feedback
