A wind that changes its direction in a counter clockwise motion. An example would be a Northwest wind changing to a West wind.

Wind that is changing direction in a counterclockwise manner. A backing wind is usually a sign of deteriorating weather conditions.

A change in wind direction running counterclockwise, as in from west to southwest.

A wind that shifts in a counterclockwise direction with height. For example, an east wind at 850 mb and a north wind at 700 mb would be a backing wind. Also can be a wind shift at the surface or a particular pressure level in which over time the wind shifts in a counterclockwise direction at a point location.

Shifting of the wind in a counterclockwise direction, usually resulting from the approach of a low-pressure system.
