Journal ArticleDOI
An active Sun throughout the Maunder Minimum
TL;DR: In this paper, the dates of maxima and minima of the Maunder Minimum can now be reliably estimated by measuring the 10Be concentration in the Dye 3 ice core.
Journal ArticleDOI
Transport and Storage of Magnetic Field by Overshooting Turbulent Compressible Convection
Steven M. Tobias,Steven M. Tobias,Nicholas H. Brummell,Thomas L. Clune,Thomas L. Clune,Juri Toomre +5 more
TL;DR: In this article, a series of numerical experiments were conducted to investigate the transport of magnetic fields by turbulent penetrative compressible convection, showing that magnetic fields preferentially transported downward out of a turbulent convecting region and stored in a stable strati-ed region below.
Journal ArticleDOI
Pumping of Magnetic Fields by Turbulent Penetrative Convection
TL;DR: In this paper, the authors show that the required transport of magnetic field from the convection zone to the overshoot region can be achieved on a convective rather than diffusive timescale by a pumping mechanism in turbulent penetrative compressible convection.
Journal ArticleDOI
Direct Statistical Simulation of Out-of-Equilibrium Jets
Steven M. Tobias,J. B. Marston +1 more
TL;DR: It is shown that, for jets near equilibrium, CE2 is capable of reproducing the jet structure (although some differences remain in the second cumulant), but as the degree of departure from equilibrium is increased (as measured by the zonostrophy parameter), the jets meander more and CE2 becomes less accurate.
Journal ArticleDOI
Downward pumping of magnetic flux as the cause of filamentary structures in sunspot penumbrae
TL;DR: It is shown that the field lines are kept submerged outside the spot by turbulent, compressible convection, which is dominated by strong, coherent, descending plumes and explains the origin of the interlocking-comb structure of the penumbral magnetic field, and the behaviour of other magnetic features near the sunspot.
