A column of cool air that sinks toward the ground. It is most often accompanied by rain.

A term applied to kilns in which the direction of travel for hot gasses, from the fire, after circulation through the ware chamber, is downward through a flue or flues in its base, to a chimney of sufficient height to draw the whole through the kiln.

a strong downward air current

downward blast of air from a thunderstorm cloud, felt at the surface as a cool gust.

Rain-cooled air that falls to the ground in a thunderstorm

A column of generally cool air that rapidly sinks to the ground, most often accompanied by precipitation in a shower or thunderstorm. Areas of downdraft usually contain little cloud, and what clouds that may be present are typically dissipating.

a relatively small-scale current of air with marked downward motion

A relatively small-scale, downward moving current of air.

A small scale downward current of air; observed on the lee side of large objects that restrict the smooth flow of air or in or near precipitation areas associated with cumuliform clouds.

Small-scale column of air that rapidly sinks toward the ground, usually accompanied by precipitation as in a shower or thunderstorm. A downburst is the result of a strong downdraft.

A sudden descent of cool or cold air to the ground, usually with precipitation, and associated with a thunderstorm or shower.

A type of kiln with the firebox and chimney at opposite ends from each other at or below the floor.

Downward flow of gases or air in a chimney or stack.
