downdraughts

Air plunging earthward

Downdraughts is the British spelling of downdrafts—downward currents of air.

In meteorology, downdraughts occur in thunderstorms when rain-cooled air plunges earthward.

In buildings, downdraughts describe cold air descending through chimneys or poorly insulated windows: The old fireplace created terrible downdraughts in winter.
