A situation in which the wind is flowing through a channel that becomes narrower at the far end causing the flow to be directed along the channel and to accelerate as the narrow end is approached. An example is wind is trapped in a valley that becomes narrower in the downwind direction. Air pollution emitted into valley air can be funneled in this manner.
