The term downdraft can also refer to a type of backdraft which occurs through chimneys which have fireplaces on the lowermost levels (such as basements) of multi-level buildings. It involves cold air coming down the chimney due to low air pressure, and makes it hard to light fires, and can push soot and carbon monoxide into domiciles.
A downburst is a strong downdraft which induces an outburst of damaging winds on or near the ground, and a microburst is a small but powerful downburst. Microburst winds can cause significant damage, and are a concern for forecasters because of their rapid onset and noted relevance for aircraft safety.
