Early-time small-scale structures in hot-exoplanet atmosphere simulations
J. W. Skinner, J. Y-K. Cho
We report on the critical influence of small-scale flow structures (e.g., fronts, vortices, and waves) that immediately arise in hot-exoplanet atmosphere simulations initialized wi…
Modons on Tidally Synchronised Extrasolar Planets
J. W. Skinner, J. Y-K. Cho
We investigate modons on tidally synchronised extrasolar planets. Modons are highly dynamic, coherent flow structures composed of a pair of storms with opposite signs of vorticity.…
Numerical Convergence of Hot-Jupiter Atmospheric Flow Solutions
J. W. Skinner, J. Y-K. Cho
We perform an extensive study of numerical convergence for hot-Jupiter atmospheric flow solutions in simulations employing a setup commonly-used in extrasolar planet studies, a res…
Sensitivity and Variability Redux in Hot-Jupiter Flow Simulations
J. Y-K. Cho, I. Polichtchouk, H. Th. Thrastarson
We revisit the issue of sensitivity to initial flow and intrinsic variability in hot-Jupiter atmospheric flow simulations, originally investigated by Cho et al. (2008) and Thrastar…
Electrodynamics on extrasolar giant planets
T. T. Koskinen, R. V. Yelle, P. Lavvas +1
Strong ionization on close-in extrasolar giant planets suggests that their atmospheres may be affected by ion drag and resistive heating arising from wind-driven electrodynamics. R…
Intercomparison of General Circulation Models for Hot Extrasolar Planets
Inna Polichtchouk, James Y-K. Cho, Chris Watkins +3
We compare five general circulation models (GCMs) which have been recently used to study hot extrasolar planet atmospheres (BOB, CAM, IGCM, MITgcm, and PEQMOD), under three test ca…
