blow down
Gust knocks over
To blow down is for wind to knock something over or flatten it: The storm blew down several trees.
A blowdown is the resulting debris—fallen timber from wind damage.
In industrial contexts, blowdown refers to releasing pressure or draining liquid from a boiler or tank to remove sediment.
