GEOG 2050 Study Guide - Midterm Guide: Lapse Rate, Outgassing, Dew Point
Document Summary
Subpolar low: energy available for weather vapor content, function of temperature. H2o: saturation, when the air mass cannot hold any more water vapor, temperature dependant. Addition of water vapor reduces evaporation and increases condensation. Max specific humidity for a given temp = the most water vapor (g) an air mass can hold = saturation. = m a s s o f w a t e r v a p o r ( g ) m a s s o f a i r ( k g ) The amount of water vapor (moisture) in an air mass. Note: for a given air mass, the mass remains constant as pressure and temperature change. Environmental lapse rate (elr) is the rate of the surrounding air. If we rise an air parcel until it is saturated, rh =100% The elevation is 1400 m and the temp is 11 c at saturation.
