A Thermal Plume Model for the Martian Convective Boundary Layer [PDF]
, 2013 The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.

Stellar Convective Penetration: Parameterized Theory and Dynamical Simulations
The Astrophysical Journal, 2022 Abstract Most stars host convection zones in which heat is transported directly by fluid motion, but the behavior of convective boundaries is not well-understood. Here, we present 3D numerical simulations that exhibit penetration zones: regions where the entire luminosity could be carried by radiation, but where the temperature gradient ...

Solar differential rotation and meridional flow: The role of a subadiabatic tachocline for the Taylor-Proudman balance [PDF]
, 2005 We present a simple model for the solar differential rotation and meridional circulation based on a mean field parameterization of the Reynolds stresses that drive the differential rotation.

Evaluation of the Plant–Craig stochastic convection scheme (v2.0) in the ensemble forecasting system MOGREPS-R (24 km) based on the Unified Model (v7.3) [PDF]
Geoscientific Model Development, 2016 The Plant–Craig stochastic convection parameterization (version 2.0) is implemented in the Met Office Regional Ensemble Prediction System (MOGREPS-R) and is assessed in comparison with the standard convection scheme with a simple stochastic scheme only ...

Global Simulation of the Madden–Julian Oscillation With Stochastic Unified Convection Scheme
Journal of Advances in Modeling Earth Systems, 2023 A new spectral convection scheme, the stochastic unified convection scheme (stochastic UNICON), is implemented in a general circulation model. The global climate simulation using stochastic UNICON is evaluated and compared with UNICON, focusing on the ...

Galactic secondary positron flux at the Earth [PDF]
, 2009 Secondary positrons are produced by spallation of cosmic rays within the interstellar gas. Measurements have been typically expressed in terms of the positron fraction, which exhibits an increase above 10 GeV. Many scenarios have been proposed to explain

The location of diapycnal mixing and the meridional overturning circulation [PDF]
, 2002 The large-scale consequences of diapycnal mixing location are explored using an idealized threedimensional model of buoyancy-forced flow in a single hemisphere. Diapycnal mixing is most effective in supporting a strong meridional overturning circulation (
