Scaling analysis of curved fronts : validity of the balance equations and semigeostrophy

Strongly curved fronts occur when the ratios of cross-front to alongfront horizontal velocities and scales are comparably small for an order one distance in the alongfront direction. To address the balances in curved frontal flow, the equations are given in cylindrical coordinates.
