The dynamics of the Changma rains in the early summer, which derive from baroclinic disturbances that are strongly modified by latent heat release, remain poorly understood.

The full development of a medicane often necessitates the formation of a large-scale baroclinic disturbance transitioning late in its life cycle into a tropical cyclone-like system, nearly always under the influence of a deep, cut-off, cold-core low within the middle-to-upper troposphere, frequently resulting from abnormalities in a wide-spreading Rossby wave massive meanders of upper-atmospheric winds.
