An analytic conceptual model of extratropical cyclones

An analytic conceptual model has been developed describing the nonlinear development of small and large extratropical cyclones towards a mature stage.
The model shows the self-development and self-limiting processes of an extratropical cyclone and reveals the existence of A- and B-development, as described by Petterssen and Smebye.
Even a so-called 'synoptic bomb' can be simulated.
