Solar Surface Convection [PDF]
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 ...

Mesoscale cellular convection: is it convection? [PDF]
The three convective instability models that aim to account for the broad aspect ratio of mesoscale cellular convection (MCC) are compared with a simple analytical version of the mesoscale entrainment instability (MEI) model proposed by Fiedler (1984). The inadequacies of the convective models are demonstrated.

AbstractDeep convection over tropical oceans often appears intensified at the edge of convectively active regions, both in idealized studies and in observations. This edge intensification of convection is studied in detail here, using the steady state of a radiative‐convective equilibrium study, marked by a single convective cluster with deep ...

This work added semi-Lagrangian convected air particles to the Intermediate Complexity Atmospheric Research (ICAR) model. The ICAR model is a simplified atmospheric model using quasi-dynamical downscaling to gain performance over more traditional ...

Theories of convection and the spectrum of turbulence in the solar photosphere [PDF]
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.

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

Development of convection along the SPCZ within a Madden-Julian oscillation [PDF]
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 ...

Converging and diverging convection around axisymmetric magnetic flux tubes [PDF]
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.

A benchmark study on mantle convection in a 3-D spherical shell using CitcomS [PDF]
As high-performance computing facilities and sophisticated modeling software become available, modeling mantle convection in a three-dimensional (3-D) spherical shell geometry with realistic physical parameters and processes becomes increasingly feasible.
