Transition to finger convection in double-diffusive convection [PDF]
Physics of Fluids, 2014 Finger convection is observed experimentally in an electrodeposition cell in which a destabilizing gradient of copper ions is maintained against a stabilizing temperature gradient. This double-diffusive system shows finger convection even if the total density stratification is unstable.

Self-Similar Accretion Flows with Convection [PDF]
Astrophys.J. 539 (2000) 798-808, 1999 We consider height-integrated equations of an advection-dominated accretion flow (ADAF), assuming that there is no mass outflow. We include convection through a mixing length formalism. We seek self-similar solutions in which the rotational velocity and sound speed scale as R^{-1/2}, where R is the radius, and consider two limiting prescriptions for ...

A benchmark study on mantle convection in a 3‐D spherical shell using CitcomS [PDF]
Geochemistry, Geophysics, Geosystems, 2008 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.

The Dominance of Neutrino-Driven Convection in Core-Collapse Supernovae [PDF]
, 2012 Multi-dimensional instabilities have become an important ingredient in core-collapse supernova (CCSN) theory. Therefore, it is necessary to understand the driving mechanism of the dominant instability. We compare our parameterized three-dimensional CCSN simulations with other buoyancy-driven simulations and propose scaling relations for neutrino-driven

Sub-mesoscale observations of convective cold pools with a dense station network in Hamburg, Germany [PDF]
Earth System Science Data, 2022 From June to August 2020, an observational network of 103 meteorological ground-based stations covered the greater area (50 km × 35 km) of Hamburg (Germany) as part of the Field Experiment on Sub-mesoscale Spatio-Temporal variability at Hanseatic city ...

Mesoscale cellular convection: is it convection? [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 1985 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.

Convection effect on two-dimensional dynamics in the nonlocal reaction-diffusion model [PDF]
Компьютерные исследования и моделирование, 2011 Pattern formation described by the scalar Fisher-Kolmogorov-Petrovsky-Piscounov equation with nonlocal competition loses and convection linear on coordinates is considered numerically.

Journal of Advances in Modeling Earth Systems, 2019 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 ...
