In air pollution, looping plume refers to:
1
when there exists a strong super adiabatic lapse rate above a surface inversion
2
a plume occurring under sub-adiabatic conditions which produces slightly stable environment
3
when an inversion layer occurs at a short distance above the top of the stack, and super adiabatic conditions prevail below the stack
4
a plume having a wavy character and occurring in super-adiabatic environment which produces highly unstable environment
