Latent heat is energy that is absorbed and stored when a substance changes state from a liquid to a gas or from a solid to a liquid. Latent heat is transferred when water evaporates from a land or water surface and is important in moving large amounts of energy from one region to another. As solar radiation flows through the atmosphere, energy is scattered and absorbed by gas molecules and dust particles in the air. CO2 and water vapor absorb incoming shortwave radiation and outgoing longwave radiation from the earth. They re-emit this radiation in all directions with part of it returning to the earth's surface in counterradiation .
Net radiation is the difference between all incoming and all outgoing radiation.
As a result, global and atmospheric circulation systems transport energy from lower to higher latitudes. Distinguish between sensible heat and latent heat. Define net radiation.
