dc.description.abstract | A numerical diagnosis for tropical cyclogenesis is proposed based on near-cloud-resolving atmosphere simulation. Calculation and analyses of helical and energetic characteristics together with hydro- and thermodynamic flow fields aloe the diagnosis of tropical cyclogenesis as an event when the primary and secondary circulations become linked on systems scales thereby making the nascent large-scale vortex helical. A key process of vertical vorticity generation from horizontal components and its amplification by special convective coherent structures - Vortex Hot Towers (VHTs) - is highlighted. The process is found to be a pathway for generation of a velocity field with linked vortex lines of horizontal and vertical vorticity on local and systems scales. the role of VHTs as connectors of the primary and secondary circulation is emphasized. | en_US |
