Chemical physics of tropical cyclogenesis

A numerical analysis of a few-parameter nonlinear model of regional large-scale cyclogenesis is performed, which makes it possible to investigate the role of solar activity, solar-terrestrial relations, El Nino, and other factors in the seasonal behavior of cyclogenesis. It was shown that, the few-parameter nonlinear model allows the realization of different scenarios of the temporal dynamics of regional large-scale tropical cyclogenesis, which can be achieved by adjusting the model parameters. For example, it is possible to simulate the formation of a different number of tropical cyclones with different characteristics in the active season, i.e., to describe the intensity of cyclogenesis with a variable number of crisis events.
