Backing is a term, in meteorology, that refers to an anti-clockwise change of direction of a wind with increasing altitude. The corresponding opposite term is veering. The definition of veering is a wind pattern in which the wind direction aloft changes in a clockwise direction relative to that near the Earth surface.

An alternative usage of these two terms is as follows:

• Backing to indicate wind direction at a given height is changing anti-clockwise with time
• Veering to indicate wind direction at a given height is changing clockwise with time
