What can Hurricane SAM (2021) tell us about ocean waves under tropical cyclones?
Xiaolu Zhao, Ludivine Oruba, Danièle Hauser +2
We investigate the ocean wave field under Hurricane SAM (2021). Whilst measurements of waves under Tropical Cyclones (TCs) are rare, an unusually large number of quality in situ an…
B{é}nard convection in a slowly rotating penny shaped cylinder subject to constant heat flux boundary conditions
A M Soward, L Oruba, E Dormy
We consider axisymmetric Boussinesq convection in a shallow cylinder radius, L, and depth, H (<< L), which rotates with angular velocity about its axis of symmetry aligned to t…
The inertial wave activity during spin-down in a rapidly penny shaped cylinder. Part II The inertial wave of maximum frequency trigger
L. Oruba, A. M. Soward, E. Dormy
In an earlier paper, Oruba, Soward & Dormy (J.Fluid Mech., vol.818, 2017, pp.205-240) considered the primary quasi-steady geostrophic (QG) motion of a constant density fluid of vis…
The inertial wave activity during spin-down in a rapidly rotating penny shaped cylinder. Part I The quasi-geostrophic trigger
L. Oruba, A. M. Soward, E. Dormy
In a previous paper, Oruba, Soward & Dormy (J.Fluid Mech., vol.818, 2017, pp.205-240) considered the primary quasi-steady geostrophic (QG) motion of a constant density fluid of vis…
Formation of eyes in large-scale cyclonic vortices
Ludivine Oruba, Peter Davidson, Emmanuel Dormy
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 vert…
Three Branches of Dynamo Action
Emmanuel Dormy, Ludivine Oruba, Ludovic Petitdemange
In addition to the weak-dipolar state and to the fluctuating-multipolar state, widely discussed in the literature, a third regime has been identified in Dormy (2016). It correspond…
On the role of thermal boundary conditions in dynamo scaling laws
Ludivine Oruba
In dynamo power-based scaling laws, the power injected by buoyancy forces is measured by a so-called flux-based Rayleigh number, denoted as (see Christensen and…
Spin-down in a rapidly rotating cylinder container with mixed rigid and stress-free boundary conditions
Ludivine Oruba, Andrew Soward, Emmanuel Dormy
A comprehensive study of the classical linear spin-down of a constant density viscous fluid (kinematic viscosity ν) rotating rapidly (angular velocity Ω) inside an axisymmetric cyl…
Eye Formation in Rotating Convection
L. Oruba, P. A. Davidson, E. Dormy
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 th…
Transition between viscous dipolar and inertial multipolar dynamos
Ludivine Oruba, Emmanuel Dormy
We investigate the transition from steady dipolar to reversing multipolar dynamos. The Earth has been argued to lie close to this transition, which could offer a scenario for geoma…
Predictive Scaling Laws for Spherical Rotating Dynamos
Ludivine Oruba, Emmanuel Dormy
State of the art numerical models of the Geodynamo are still performed in a parameter regime extremely remote from the values relevant to the physics of the Earth's core. In order…
