Woodsmoke usually sinks to the ground level

What's the use of having a smokestack 2 feet higher than a neighbor's roof?
Woodsmoke usually sinks to the ground level:

The standard Briggs Plume equations would not apply to short chimneys,
as these only are modeled for very tall (300 ft) industrial smokestacks.

This can happen, but 'usually' is a bit over the top. Usually the smoke goes up, because usually it's cold enough and the smoke is hot enough that it sufficiently rises out of the way in my experience.

Yes I agree, when it is very cold (≤ 0°F) smoke can rise vertically IF there is no wind.
Unfortunately, in milder temps (discovered through many observations I have made) smoke sinks like a stone.
Especially in the summertime, when fire pit smoke is released at ground level, and pretty much stays there.
