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 ... Witryna2 lut 2012 · Fumigating Plume • Fumigating plume (cont) • unstable air causes the plume to move up and down - can cause localised pollution. • become looping or coning plumes as the air conditions stabilise.
