It is primarily the surface wind direction that determines whether the wind is backing or veering with height It seems that a front either provides or releases some form of friction to, quite suddenly, change the balance of forces that makes the wind blow in a certain direction. A backing wind turns counterclockwise with height.

I've always understood, and observed, that winds veer with the passage of a front (warm or cold) in the northern hemisphere
A look at any weather map confirms the isobars 'veer' behind most fronts.
The wind veers across a front, it doesn't matter whether it is warm or cold One can show from margules' equation that it is necessary for wind shear to exist across a frontal surface, this being cyclonic in the northern hemisphere. Learn what is the wind direction and how to read it from the experts of the leading pro weather app for outdoors Since the wind veers with height through the layer, the front would be warm
The vertical wind shift through a frontal zone depends on the direction of the slope In cold fronts the wind backs with height, while in warm fronts the wind veers with height. Just before a front passes, the wind may back a little more before it veers at the front A trough can simply be a bend in the isobars created perhaps by a lot of convection or, maybe, the downstream effect of high ground.
When you fly through a cold front or warm front, will the wind veer or back
We had a great question come in recently (thanks derek!) asking if conrad could explain about the wind conditions found at cold and warm fronts.
