Meteorology Back-door cold frontBacking Wind

Backing Winds - 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 - 1. According to general internationally accepted usage, a change in wind direction in a counterclockwise sense (e.g., south to southeast to east) in either hemisphere of the earth; the opposite of veering. 2.

BACKING A counterclockwise shift in the wind direction in the Northern Hemisphere at a certain location. In the Southern Hemisphere, it is clockwise. This can either happen in the horizontal or the vertical (with height).

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.

BACKING WIND- A wind direction that turns counterclockwise with height. An indication of cold air advection.

Backing- relates to time trend and wind direction; backing winds trend counter-clockwise and are indicative of cold air advection.

backing—Shifting of the wind in a counterclockwise direction with respect to either space or time; opposite of veering.


Backing Wind Shift - A wind shift in a counterclockwise direction, such as a shift from east to north.
Barograph - A recording barometer.

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

Backing:A counter-clock movement in the wind direction.
Back Door Cold Front: When a cold fron moves from east to west.
Backing: When the wind moves counter-clock-wise.

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.

BACKING A change in wind direction that shifts counterclockwise in the Northern Hemisphere at a certain location. In the Southern Hemisphere, it is clockwise. This can either happen in the horizontal or the vertical (with height).

Backing A change in wind direction in a counterclockwise sense; opposite of veering. Backlash The play or loose motion in an instrument due to the clearance existing between mechanically contacting parts.

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.

Veering and Backing Winds In meteorology, "veering" and "backing winds" are terms used to describe the manner in which winds are shifting or changing.

This display is useful for observing local changes in vertical wind shear, such as backing of low-level winds, increases in speed shear, and development or evolution of nearby jet streams (including low-level jets).

In storm spotting, a backing wind usually refers to the turning of a south or southwest surface wind with time to a more east or southeasterly direction.

This is due to the wind speed increasing rapidly with height and the wind direction either veering or backing rapidly with height.SupercoolTo cool a liquid below its freezing point without solidification or crystallization.

Compare with backing winds.

a geostrophic wind that advects warm air into a region of colder air causes the wind to turn right (clockwise, veering) with height, while cold air advection into a region of warmer air results in the wind turning left (counter-clockwise, backing).

Not having the benefit of radar, it will seem to citizens living in an area receiving repeated, short-term precipitation bursts that the storm is backing up and moving across again and again. This is a popular but erroneous notion.

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 backing winds.

A Bulk Richardson Number of between 15 and 35 favor supercell development. Typically, the hodograph will look like a horse shoe. This is due to the wind speed increasing rapidly with height and the wind direction either veering or backing rapidly ...
