A Study of Flares in the Ultra-Cool Regime from SPECULOOS-South by Murray, CA, Queloz, D, Gillon, M, Demory, BO, Triaud, AHMJ, de Wit, J, Burdanov, A, Chinchilla, P, Delrez, L, Dransfield, G, Ducrot, E, Garcia, LJ, Chew, Y Gómez Maqueo, Günther, MN, Jehin, E, McCormac, J, Niraula, P, Pedersen, PP, Pozuelos, FJ, Rackham, BV, Schanche, N, Sebastian, D, Thompson, SJ, Timmermans, M, Wells, R

“…By extending previous M dwarf flare studies into the ultra-cool regime, we find M5–M7 stars are more likely to flare than both earlier, and later, M dwarfs. …”

Transport and emergent stratification in the equilibrated Eady model: the vortex-gas scaling regime by Gallet, Basile, Miquel, Benjamin, Hadjerci, Gabriel, Burns, Keaton J, Flierl, Glenn R, Ferrari, Raffaele

“…Through a suite of numerical simulations, we show that the transport properties of the resulting turbulent flow are governed by quasigeostrophic (QG) dynamics in the rapidly rotating strongly stratified regime. The ‘vortex gas’ scaling predictions put forward in the context of the two-layer QG model carry over to this fully three-dimensional system: the functional dependence of the meridional flux on the control parameters is the same, the two adjustable parameters entering the theory taking slightly different values. …”

Multiple regimes of air-sea carbon partitioning identified from constant-alkalinity buffer factors by Goodwin, Philip, Omta, Anne Willem, Follows, Michael J

“…We show that the qualitative changes are connected with different regimes in ocean chemistry: if the air-sea partitioning of carbon is determined by the carbonate ion, then the Revelle factor increases with emissions, whereas the buffer factor decreases with emission size, when dissolved carbon dioxide determines the partitioning. …”

On the Feedback of Ice–Ocean Stress Coupling from Geostrophic Currents in an Anticyclonic Wind Regime over the Beaufort Gyre by Wang, Qiang, Marshall, John C., Scott, Jeffery R., Meneghello, Gianluca, Danilov, Sergei, Jung, Thomas

“…In this paper we explore how this feedback can significantly contribute to BG stabilization in an anticyclonic wind regime. We use an ice-ocean model and turn on and off the feedback in simulations to elucidate the role of the feedback. …”

DOPPLER SIGNATURES OF THE ATMOSPHERIC CIRCULATION ON HOT JUPITERS by Showman, Adam P., Fortney, Jonathan J., Lewis, Nikole, Shabram, Megan

“…We present state-of-the-art circulation models including non-gray radiative transfer to quantify this regime shift and the resulting Doppler signatures; these models suggest that cool planets like GJ 436b lie in the first regime, HD 189733b is transitional, while planets hotter than HD 209458b lie in the second regime. …”

Scaling laws for convection and jet speeds in the giant planets by Showman, Adam P., Kaspi, Yohai, Flierl, Glenn Richard

“…We show based on mixing-length estimates that if such a regime exists, mean jet speeds should scale as heat flux to the 1/4 power. …”

THREE-DIMENSIONAL ATMOSPHERIC CIRCULATION OF HOT JUPITERS ON HIGHLY ECCENTRIC ORBITS by Kataria, T., Showman, A. P., Lewis, Nikole, Fortney, Jonathan J., Marley, Mark S., Freedman, Richard S.

“…Such orbits lead to time-variable stellar heating, which has major implications for the planet's atmospheric dynamical regime. However, little is known about the fundamental dynamical regime of such planetary atmospheres, and how it may influence the observations of these planets. …”

A Review of Parameterizations for Enthalpy and Momentum Fluxes from Sea Spray in Tropical Cyclones by Sroka, Sydney Glass, Emanuel, Kerry Andrew

“…This paper seeks to review the developments in parameterizations of the sea spray-mediated enthalpy and momentum fluxes for the high wind speed regime and to synthesize key findings that are common across many investigations.…”

Reassessing the Climate Change Narrative by Lindzen, Richard S., Christy, John R.

“…We note that the atmosphere has distinct tropical and extratropical regimes. The tropical regime is significantly dependent on the greenhouse effect and is characterized by temperatures that are largely horizontally homogenized. …”

3D-PTV measurements in a plane Couette flow by Krug, Dominik, Lüthi, Beat, Holzner, Markus, Tsinober, Arkady, Seybold, Hansjorg

“…Results are analyzed in terms of basic flow properties, and a clear distinction of flow regimes (laminar for Re < 320, transitional for 320 < Re < 400, and turbulent when Re > 400) could be made. …”

Earthquake rupture below the brittle-ductile transition in continental lithospheric mantle by Prieto, German A., Froment, Berenice, Abercrombie, Rachel, Yu, Chunquan, Poli, Piero

“…Our results imply that earthquake nucleation in the lithospheric mantle is not exclusively limited to the brittle regime; weakening mechanisms in the ductile regime can allow earthquakes to initiate and propagate. …”

Quantifying the Eddy Feedback and the Persistence of the Zonal Index in an Idealized Atmospheric Model by Chen, Gang R., Plumb, R. Alan

“…The model can generate a nearly identical climatology and leading mode of the zonal mean zonal wind for different frictional damping rates, except when the jet undergoes a regime transition. For those experiments without a regime transition, as the surface friction is increased, the strength of eddy feedback is enhanced but the zonal index becomes less persistent. …”

Propagating Annular Modes: Empirical Orthogonal Functions, Principal Oscillation Patterns, and Time Scales by Sheshadri, Aditi, Plumb, R. Alan

“…Results from Southern Hemisphere ERA-Interim data are partly consistent with the behavior of the model's propagating regime. Among other things, these results imply that the time scale that determines the sensitivity of a model to external forcing might be different from the decorrelation time of the leading PC and involves both the rate of decay of the dynamical mode and the period associated with propagation. …”

Inverse cascade suppression and shear-layer formation in magnetohydrodynamic turbulence subject to a guide field and misaligned rotation by Benavides, Santiago J, Burns, Keaton J, Gallet, Basile, Cho, James Y-K, Flierl, Glenn R

“…Starting with a two-dimensional inverse energy cascade at zero rotation, the flow first transitions to a forward cascade of kinetic energy, then to a shear-layer dominated regime and finally to a second shear-layer regime where the kinetic energy flux is strongly suppressed and the energy transfer is mediated by the induced magnetic field. …”

Efficiency of compaction and compositional convection during mafic crystal mush solidification: the Sept Iles layered intrusion, Canada by Namur, Olivier, Charlier, Bernard

“…The change from a channel flow regime that dominates in troctolites to a porous flow regime in gabbros results from the increasing efficiency of compaction with differentiation due to higher density contrast between the cumulus crystal matrix and the equilibrium melts and to the bottom-up decreasing rate of crystal accumulation in the magma chamber.…”
