WitrynaLofting. Self-lofting is a phenomenon that may occur if a plume maintains or increases its buoyancy as a result of heat absorption from the sun. From: Oil Spill Science and … WitrynaLofting plume If the plume is released just under an inversion layer, a serious air pollution situation could develop. As the ground warms in the morning, air below an inversion layer becomes unstable. When the instability reaches the level of the plume that is still trapped below the inversion layer, the pollutants can be rapidly transported ...
Witrynaplume rarely reaches the grounds level unless the inversion is broken by surface heating or a topographical barrier such as a hill. At night, with light winds and clear skies, fanning plumes are quite common. E. Lofting plume: It diffuses upward but not downwards and occurs when there is a super-adiabatic
