The understanding of the transport of trace chemical species between the stratosphere and the troposphere is necessary for global change prediction. Until recently it was believed that stratospheric inputs, through jet streaks and tropopause folding, should occur only at extratropical latitudes. A
## Abstract Theoretical models of frontogenesis using the semiβgeostrophic approximation have imagined the process to occur between airβmasses whose only difference is their respective surface potential temperature. This is equivalent to assuming the Ertel potential vorticity (PV) to be constant in
