What Is Air Mass Modification?
The way an air mass changes as it moves away from where it formed, picking up or losing heat and moisture from the ground or water beneath it. In technical terms: Alteration of an air mass's temperature, moisture, and stability by surface fluxes of sensible and latent heat, radiation, subsidence, and mixing during transit.
Air Mass Modification In Plain English
The way an air mass changes as it moves away from where it formed, picking up or losing heat and moisture from the ground or water beneath it.
The Technical Definition
Alteration of an air mass's temperature, moisture, and stability by surface fluxes of sensible and latent heat, radiation, subsidence, and mixing during transit; cold air over warm water is destabilized from below (e.g., lake-effect snow), while warm air over cold surfaces is stabilized and may produce advection fog.
