air funnel

The yellow one has blunt ends and bulbous projections vaguely like air funnels on a ship.

Sirocco can warp nearby weather patterns to create swirling air funnels that can strike with concussive impact or lift him into the air.

The increase in temperature is caused by the geography of the region; cool air funnels down the Chetco River valley from the Siskiyou and Coast ranges, gradually heating up before eventually reaching Brookings as a warm wind.
