  journal={arXiv: Fluid Dynamics},
We present numerical simulations of steady, laminar, axisymmetric convection of a Boussinesq fluid in a shallow, rotating, cylindrical domain. The flow is driven by an imposed vertical heat flux and shaped by the background rotation of the domain. The geometry is inspired by that of tropical cyclones and the global flow pattern consists of a shallow, swirling vortex combined with a poloidal flow in the r-z plane which is predominantly inward near the bottom boundary and outward along the upper… 
Dynamics of a trapped vortex in rotating convection
© 2019 American Physical Society. We consider axisymmetric rotating convection in a cylindrical domain, focusing on the eye that can form at the center of a cyclonic vortex. Upon increasing the
Estimation of characteristic vortex structures in complex flow
ABSTRACT We present a systematic approach to extract the characteristic vortex region that contains the essential features of a complex flow field. The process involves the analysis of the complex
Inertial wave activity during spin-down in a rapidly rotating penny shaped cylinder
Abstract In an earlier paper, Oruba et al. (J. Fluid Mech., vol. 818, 2017, pp. 205–240) considered the primary quasi-steady geostrophic (QG) motion of a constant density fluid of viscosity $\nu$
A Remarkable Use of Energetics by Nature: The Chaotic System of Tropical Cyclones
Tropical cyclones, also called hurricanes or typhoons, appall mankind and devastate our environment. Formed during the hot season, tropical cyclones act like valves releasing the heat accumulated in

The problem formulated in Part 1 (Loper, J. Fluid Mech., vol. 892, 2020, A16) for flow in the turbulent boundary layer beneath a vortex is solved for a power-law swirl: $v_{\infty }(r)\sim
Characterising and predicting the movement of clouds using fractional-order optical flow
The optical flow is utilized to localize the high alert regions to have a better localization and motion signatures, and a fractional order technique to compute optical flow based interpolation and Advection-anisotropic-diffusion based extrapolation model give promising results.
On the inertial wave activity during spin-down in a rapidly rotating penny shaped cylinder: a reduced model
In a previous paper, Oruba et al. (J. Fluid Mech., vol. 818, 2017, pp. 205–240) considered the ‘primary’ quasi-steady geostrophic (QG) motion of a constant density fluid of viscosity


Eye formation in rotating convection
We consider rotating convection in a shallow, cylindrical domain. We examine the conditions under which the resulting vortex develops an eye at its core; that is, a region where the poloidal flow
The thermodynamic speed limit and its violation in axisymmetric numerical simulations of tornado‐like vortices
Abstract Processes that regulate the central pressure and maximum wind speeds of tornado‐like vortices are explored with an axisymmetric numerical model. The model consists of a rotating cylinder of

Secondary circulations in rotating-flow boundary layers
The rotating-flow boundary layer is a special case of the more general threedimensional boundary layer in which the pressure gradient imposed by the outer flow (above the boundary layer) is not in

The Fluid Dynamics of Tornadoes
Because of the difficulty in making measurements under controlled conditions, most of what is known about the fluid dynamics of tornadoes comes from laboratory experiments that produce vortices with
