A counter-clockwise change in wind direction. For example, from southwest to southeast, through south. It is the opposite of veering wind.

s - Winds which shift in a counterclockwise direction with time at a given location (e.g. from southerly to southeasterly), or change direction in a counterclockwise sense with height (e.g.
BACKING WINDS: A counterclockwise change in wind direction. Backing winds with height are indicative of cold air advection (CAA).
BAR: An obstacle formed at the shallow entrance to the mouth of a river or bay.
- A wind direction that turns counterclockwise with height. An indication of cold air advection.
Backing Wind Shift - A wind shift in a counterclockwise direction, such as a shift from east to north.
Barograph - A recording barometer.
- A wind that changes its direction in a counter clockwise motion. An example would be a Northwest wind changing to a West wind.
Backing Wind- Shifting of the wind in a counterclockwise direction, usually resulting from the approach of a low-pressure system.
Barograph- An instrument that provides a continuous record of atmospheric pressure.
Veering and s In meteorology, "veering" and "s" are terms used to describe the manner in which winds are shifting or changing.
For example, a wind changing in height from south near the ground to southwest at 5,000 feet and finally to west at 10,000 feet. This is indicative of warm air advection. Compare with backing winds.
In storm spotting, a usually refers to the turning of a south or southwest surface wind with time to a more east or southeasterly direction.
Backing- relates to time trend and wind direction; backing winds trend counter-clockwise and are indicative of cold air advection.
or which change direction in a clockwise sense with height (e.g., southeasterly at the surface turning to southwesterly aloft). The latter example is a form of directional shear which is important for tornado formation. Compare with s.
Veering/Backing of wind: When a wind direction changes such that it moves with the clock, e.g. from east to south through south-east, that is a veering wind; A wind therefore that changes against the normal clock motion is a backing wind.
typically don't last as long as their "right mover" cousins and they usually only produce large hail (¾" in diameter or greater) and severe wind gusts in the excess of 50 knots (58 mph). Left Movers are favored when you have s.
Compare with backing winds.Velocity Azimuth DisplayA WSR 88-D product which shows the radar derived wind speeds at various heights. This radar product shows the wind speeds from 2,000 to 55,000 feet above the ground.
