WebAug 16, 2024 · where g is the gravitational acceleration, c pd is the specific heat at constant pressure of dry air, r v is the mixing ratio of water vapor, L v is the latent heat of vaporization, R is the gas constant for dry air, ϵ is the ratio of the gas constants for dry air and water vapor, and T is temperature. This expression is an approximation for both the … WebLatent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.. …
WebApr 5, 2024 · Humidity has two main effects on the energy budget and, as a result, on temperature. Water vapour in the atmosphere, for example, contains "latent" energy. This latent heat is absorbed from the surface liquid during transpiration or evaporation, cooling the earth's surface. At the surface, this is the largest non-radiative cooling effect. http://www.physicalgeography.net/fundamentals/6c.html
