Effects of Magnetic Fields on Solar Inertial Modes in Global Nonlinear Simulations
Conrado S. Finotti, Gustavo Guerrero, Santiago A. Triana +2
Solar inertial modes are increasingly viewed as probes of the solar interior, with recent helioseismic evidence indicating that these modes may be sensitive to the internal magneti…
Simulations of the onset and dynamical evolution of inertial waves in solar/stellar interior
Mariane D. Souza-Gomes, Conrado S. Finotti, Gustavo Guerrero +4
Inertial modes have been recently detected in the Sun via helioseismology, yet their origin, evolution, and role in the dynamics of the solar plasma and magnetic field remain poorl…
Adaptively Implicit Advection for Atmospheric Flows
Hilary Weller, Christian Kuehnlein, Piotr K. Smolarkiewicz
Implicit time-stepping for advection is applied locally in space and time where Courant numbers are large, but standard explicit time-stepping is used for the remaining solution wh…
Implicit large eddy simulations of global solar convection: effects of numerical resolution in non-rotating and rotating cases
G. Guerrero, A. M. Stejko, A. G. Kosovichev +2
Simulating deep solar convection and its coupled mean-field motions is a formidable challenge where few observational results constrain models that suffer from the non-physical inf…
Numerical convergence of 2D solar convection in implicit large-eddy simulations
H. D. Nogueira, G. Guerrero, P. K. Smolarkiewicz +1
Large-eddy simulations (LES) and implicit LES (ILES) are wise and affordable alternatives to the unfeasible direct numerical simulations (DNS) of turbulent flows at high Reynolds n…
Mixed-precision for Linear Solvers in Global Geophysical Flows
Jan Ackmann, Peter D. Düben, Tim N. Palmer +1
Semi-implicit time-stepping schemes for atmosphere and ocean models require elliptic solvers that work efficiently on modern supercomputers. This paper reports our study of the pot…
