What happens to smoke in a chimney on a windy day?

On a windy day, the smoke from a chimney can be affected by the wind's movement, causing it to disperse more quickly and possibly blow back down into the chimney. Wind can create turbulence, which may disrupt the upward flow of smoke, leading to potential downdrafts. This can result in poor draft conditions, causing smoke to escape into the living space rather than venting properly outside. Overall, windy conditions can complicate the effective functioning of a chimney.
