Turbulent vortex dynamo in the Earth’s atmosphere and the emerging opportunity to affect tropical cyclogenesis

Abstract

The interpretation of tropical cyclogenesis as an extreme threshold event in the helical atmospheric turbulence allows us to discuss the idea on affecting the birth of a hurricane. A hypothetical way is based on the crucial role of the intense vortical cloud convection, known as Vortical Hot Towers, in the excitation and maintenance of large-scale helical-vortex instability. Some quantitative estimates are given, for which results of idealized cloud-resolving numerical simulation have been applied. The modern numerical modeling of atmospheric processes makes it possible to investigate and evaluate the possibilities of managing the instability, for example, on the basis of “Hurricane Nature Run.”
