(from the article `Buys Ballot`s law`) Theoretically, the relationship states that the angle between the wind and the pressure gradient is a right angle. This is almost exactly true in the ... ...to lines of equal pressure (isobars) in a rotating system, such as the Earth. Such flow is produced by the balance of the Coriolis force (q.v....
