The Unsteady Taylor--Vortex Dynamo is Fast
Liam O'Connor, Daniel Lecoanet, Geoffrey M. Vasil +6
Astrophysical and geophysical fluids commonly generate organized magnetic fields, despite having enormous magnetic Reynolds numbers and abundant small-scale turbulence. F…
Rapidly Rotating Wall-Mode Convection
Geoffrey M. Vasil, Keaton J. Burns, Daniel Lecoanet +3
In the rapidly rotating limit, we derive a balanced set of reduced equations governing the strongly nonlinear development of the convective wall-mode instability in the interior of…
On the Linear Stability of Partially and Fully Saturated Atmospheres to Moist Convection
Jeffrey S. Oishi, Benjamin P. Brown
We present a linear analysis of a minimal model of moist convection under a variety of atmospheric conditions. The stationary solutions that we analyze include both fully saturated…
The solar dynamo begins near the surface
Geoffrey M Vasil, Daniel Lecoanet, Kyle Augustson +5
The Sun's magnetic dynamo cycle features a distinct pattern: a propagating region of sunspot emergence appears around 30 degrees latitude and vanishes near the equator every 11 yea…
Iterative Methods for Navier--Stokes Inverse Problems
Liam O'Connor, Daniel Lecoanet, Evan H. Anders +5
Even when the partial differential equation underlying a physical process can be evolved forward in time, the retrospective (backward in time) inverse problem often has its own cha…
Ordering of timescales predicts applicability of quasi-linear theory in unstable flows
Curtis J. Saxton, Brad Marston, Jeffrey S. Oishi +1
We discuss the applicability of quasilinear-type approximations for a turbulent system with a large range of spatial and temporal scales. We consider a paradigm fluid system of rot…
