They proposed a two-step character of frontogenesis where, first, geostrophic deformation increases the temperature gradients in the growing baroclinic wave and, second, the ageostrophic frontal circulation strongly amplifies this gradient (Hoskins and Bretherton 1972).

In the late 1970s, three young British meteorological scientists at Reading University (United Kingdom) appealed to the theory of atmospheric energy dispersion when they tried to understand a numerical experiment on baroclinic instability, in particular the triggering of successive baroclinic waves (Hoskins et al.
