Which of the following is /are incorrect?
1
Lofting plume is produced by a strong super adiabatic lapse rate immediately above the stack and a negative lapse rate immediately below the stack opening.
2
Looping plume arises in a sub-adiabatic environment (ELR < ALR).
3
When the inversion layer exists above and below the stack, the plume forms are known as fumigating plumes.
4
Fanning plume formed at extreme inversion condition owing to a negative lapse rate.
