What can disperse smoke?
The following materials are believed to be capable of absorbing or neutralizing tobacco smoke odors, at least temporarily:
- vinegar. Place a bowl of vinegar in each affected room overnight.
- citrus.
- baking soda.
- coffee grounds.
- charcoal.
What makes a lot of smoke when burned?
The more intense the fire, the more complete the combustion process and a bigger percent of the smoke will be carbon dioxide and water vapor.
How does lapse rate affect the dispersal of smoke?
With a low lapse rate (more stable atmosphere) a smoke plume will not rise as high and may, once it cools, sink back to the surface with the potential to impact air quality both in the immediate vicinity or downwind.

What is the average lapse rate?
The lapse rate of nonrising air—commonly referred to as the normal, or environmental, lapse rate—is highly variable, being affected by radiation, convection, and condensation; it averages about 6.5 °C per kilometre (18.8 °F per mile) in the lower atmosphere (troposphere).
What is adiabatic lapse rate?
The adiabatic lapse rate is the rate at which the temperature of an air parcel changes in response to the compression or expansion associated with elevation change, under the assumption that the process is adiabatic, i.e., no heat exchange occurs between the given air parcel and its surroundings.
What happens to the atmosphere during smoke dispersion?
The air just above the surface becomes heated and expands. In turn, it begins to rise, since it is lighter, resulting in vertical movement in the atmosphere. The more unstable, the higher smoke will be lifted. After dark, atmospheric conditions change rapidly becoming stable.
How does the mixing height of smoke affect dispersion?
The higher the mixing height, the higher the smoke will rise although it will not reach the mixing height except possibly when fuel loading is high and the fire is very intense. This in turn allows it more room to disperse. The bottom of cumulus clouds is usually a good indicator of the mixing height.
What causes smoke to drop back down to the ground?
Any smoke still in the air will drop back down to the ground. A temperature inversion is an extreme example of stable conditions. It will act as a “lid” on the fire. The circulation around a low-pressure area causes horizontal converging of air at low levels and lifting of air near the center.
What happens to the smoke from a fire after dark?
After dark, atmospheric conditions change rapidly becoming stable. Under stable conditions, smoke will not rise except from the heat of the fire and then, only for a short distance. The fire itself will not burn as intense. Any smoke still in the air will drop back down to the ground.
