The energy-cycle analysis of the interactions between shallow and deep atmospheric convection

Dynamics of Atmospheres and Oceans, 2013
Interactions between different convection modes can be investigated using an energy–cycle description under a framework of mass–flux parameterization. The present paper systematically investigates this system by taking a limit of two modes: shallow and ...

Atmospheric Vortices in Shallow Convection

Journal of Applied Meteorology, 1988
Abstract Observations of funnel clouds over Port Phillip Bay, Victoria, Australia, indicate that they occur during outbreaks of cool air from the Southern Ocean advecting over the relatively warm bay waters. These clouds act as tracers for shallow convection vortices with dynamics similar to large dust devils.

Natural convection in a shallow cavity

Journal of Fluid Mechanics, 1987
We present numerical solutions of natural convection in a shallow enclosure heated from a side. As a result of hydrodynamic instability transverse cells appear in the flow if the Prandtl number is sufficiently small. Both conducting and insulated top and bottom boundaries were considered.

Evolution of Organized Shallow Convection

2020
<p>Uncertainty in the response of clouds to warming is the leading source of uncertainty in projections of future warming. To a large fraction the frequently occurring shallow cumulus clouds in the trade wind region contribute to this uncertainty.

Mesoscale shallow convection in the atmosphere

Reviews of Geophysics, 1996
This paper is a review of the observational, experimental, theoretical, and numerical studies of mesoscale shallow convection (MSC) in the atmosphere. Typically, MSC is 1 to 2 km deep, has a horizontal length scale of a few to a few tens of kilometers, and takes distinctive planforms: linear and hexagonal.

Convection in a Shallow Cavity

1990
The structure of longitudinal rolls of a fluid with a low Prandtl number in a differentially heated shallow cavity is considered. Computational results, carried out by a pseudo-spectral method, include the calculation of velocity and temperature fields.

Roles of deep and shallow convection and microphysics in the MJO simulated by the Model for Prediction Across Scales

Journal of Geophysical Research D: Atmospheres, 2016
The November event of the Madden‐Julian oscillation (MJO) during the Dynamics of North Atlantic Models (DYNAMO) field campaign was simulated using the global compressible nonhydrostatic Model for Prediction Across Scales with global coarse (60 and 15 km)

Natural convection in a shallow annular cavity

International Journal of Heat and Mass Transfer, 1980
Abstract The problem of natural convection in a shallow annular cavity with differentially heated inner and outer walls is considered. Compared to the two-dimensional problem Cormack, Leal and Imberger[3], the flow structure differs in two important ways. First the core flow is only parallel at O(1) in the annulus.

Natural convection in shallow water

Nonlinear Analysis: Real World Applications, 2007
Starting from the 3D Boussinesq model and taking the limit as the domain thickness tends to zero, we derive rigorously the 2D model for natural convection in shallow water. The model reduces to a degenerated elliptic equation for the pressure, an explicit formula for horizontal components of the velocity and a vertical diffusion for the vertical ...

Secondary instabilities of convection in a shallow cavity

Journal of Fluid Mechanics, 1992
Analysis of secondary instabilities of natural convection in a shallow cavity heated from a side has been carried out. For mercury with Prandtl number equal to 0.027 analysis of the primary instabilities by linear theory shows that an instability sets in as transverse cells at Grashof number equal to 9157.6.
