The numerical analysis of the nonlinear self-consistent small-parametric model (NSPM) of the regional large-scale cyclogenesis (RLSC) is continued on the base of coupled system of nonlinear equations for the mean wind velocity and ocean surface temperature inside tropical cyclone, describing the time dynamics of the strong atmospheric vortex. This model allows us to study various scenario of RLSC time dynamics. Numerical calculations have shown that by the suitable choice of NSPM parameters it is possible to obtain the RLSC annual behaviour with the generation of a given number of typhoons during the RLSC active season. The possible variations of wind velocity inside the typhoon can also be described by this model. Therefore it is possible now to study features of RLSC temporal dynamics during the active season and to investigate the dependence of RLSC characteristics on a number of external factors like the space weather.
Keywords: nonlinear equations, small-parametric model, large-scale cyclogenesis, ocean surface temperature, active season
