Solar Surface Convection [PDF]

open access: yesLiving 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]

open access: yesProceedings 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]

open access: yesSurveys 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.

Experimental and Theoretical Study on the Heat Transfer Coefficients of Building External Surfaces in the Tropical Island Region

open access: yesApplied Sciences, 2019
China is actively promoting ocean territory construction, and how to design low-energy buildings to fit the unique climate of tropical island regions has received much attention.

WRF Model Sensitivity to Spatial Resolution in Singapore: Analysis for a Heavy Rain Event and General Suitability

open access: yesAtmosphere, 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

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

open access: yes, 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.

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

open access: yes, 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.

Determination of the heat transfer coefficient by convection, according to shape of the baffles (solar air collector)

open access: yesRevue des Énergies Renouvelables, 2022
This experimental study and mathematical modelling aim to improve the heat transfer by convection in different cases of transversal baffles inside a duct of a solar air collector.

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

open access: yes, 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 ...

Magneto-convection [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Convection is the transport of energy by bulk mass motions. Magnetic fields alter convection via the Lorentz force, while convection moves the fields via the curl( v × B ) term in the induction equation.
