Solar Surface Convection [PDF]
Living Reviews in Solar Physics, 2009 We review the properties of solar convection that are directly observable at the solar surface, and discuss the relevant underlying physics, concentrating mostly on a range of depths from the temperature minimum down to about 20 Mm below the visible ...

Bidispersive-inclined convection [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 A model is presented for thermal convection in an inclined layer of porous material when the medium has a bidispersive structure. Thus, there are the usual macropores which are full of a fluid, but there are also a system of micropores full of the same fluid. The model we employ is a modification of the one proposed by Nield & Kuznetsov (2006Int. J.

Observing Convective Aggregation [PDF]
Surveys in Geophysics, 2017 Convective self-aggregation, the spontaneous organization of initially scattered convection into isolated convective clusters despite spatially homogeneous boundary conditions and forcing, was first recognized and studied in idealized numerical simulations.

Development of convection along the SPCZ within a Madden-Julian oscillation [PDF]
, 1996 A subtropical Rossby wave propagation mechanism is proposed to account for the poleward and eastward progression of intraseasonal convective anomalies along the South Pacific Convergence Zone (SPCZ) that is observed in a significant proportion of Madden ...

Atmosphere, 2022 Granularity of the grid (both horizontally and vertically) is a key consideration when conducting localised Numerical Weather Prediction (NWP) modelling. Generally speaking, an NWP model with a finer grid can explicitly resolve more processes and require

Converging and diverging convection around axisymmetric magnetic flux tubes [PDF]
, 2006 A numerical model of idealized sunspots and pores is presented, where axisymmetric cylindrical domains are used with aspect ratios (radius versus depth) up to 4.

Using Machine Learning to Parameterize Moist Convection: Potential for Modeling of Climate, Climate Change, and Extreme Events [PDF]
Journal of Advances in Modeling Earth Systems, 2018 The parameterization of moist convection contributes to uncertainty in climate modeling and numerical weather prediction. Machine learning (ML) can be used to learn new parameterizations directly from high‐resolution model output, but it remains poorly ...

Theories of convection and the spectrum of turbulence in the solar photosphere [PDF]
, 2006 Classical theories of turbulence do not describe accurately inertial range scaling laws in turbulent convection and notably fail to model the shape of the turbulent spectrum of solar photospheric convection.
