Observations and Modelling of Fronts and Frontogenesis

Here, however, a divergence drives the frontogenesis, as
fluid is drawn up at the boundary to produce horizontal
gradients from vertical stratification.
The basic physics of the upwelling process analyzed in
Chapter III should essentially apply (with appropriate
rescaling and some additional dynamics) to wind-driven
upwelling in the Subarctic gyre north of the Subtropical
Frontal Zone. Since the meridional gradient in surface layer
properties may be partially maintained by this upwelling,
further investigations may eventually link the ideas and
observations of these two Chapters in an unexpected and
relatively direct manner.
