The surface wind is taken to be a fixed angle (about 30°) veered from the direction of the gradient wind, (10° over water). So, if the gradient wind backs, the surface wind will also back.

These rough 'rules' are not of much use in practice because there are a multitude of other influences and local effects that can act to give a different result. I suppose it is reasonable to assume that the surface wind is normally found to be veered in favour of the pressure gradient.

Thank you Mr Bob tait for taking time to reply.
The answer i got from an instructor for this question (The surface wind following the passage of a warm or cold front will normally?) VEER. In the exam, im confused if i should go with veer or with back. what would you suggest is the most correct answer if i had to choose between
A. Back
B. Veer
C. Reverse direction to correspond with the isobar and pressure gradient.
I would pick back but they told me its wrong.

Thanks
