It is continued the analysis of regional large-scale cyclogenesis (RLSC) temporal dynamics on the basis of selfconsistent nonlinear small-parametric model (NSPM) containing nonlinear equations for the wind velocity and ocean surface temperature inside tropical cyclone. This model allows to study the role of solar-terrestrial relations, the space weather and other external factors on the RLSC seasonal behaviour and to investigate also different scenarios of RLSC development in the dependence on NSPM parameters. 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 and these vortices characteristics may differ significantly. 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, El-Ninio phenomena an so on.
Keywords: nonlinear equations, small-parametric model, regional cyclogenesis, tropical cyclones, ocean surface temperature, active season
