| Types of Air Plumes | Occurrence Behaviour | ||
| 1. | Looping plume | A. | Occurs under sub-adiabatic condition when wind speed exceeds 32 km per hour |
| 2. | Fanning plume | B. | Wavy character and occurs in super-adiabatic environment |
| 3. | Coning plume | C. | Occurs when there exists super adiabatic lapse rate above a surface inversion |
| 4. | Lofting plume | D. | Occurs under extreme inversion conditions caused by environmental lapse rate and plume become horizontal |
