Deep Convective Plumes in the Ocean
The mesoscale ocean circulation deep convection the atmosphere
2015/8/17
Deep convection is a process in which the mesoscale ocean circulation and atmospheric forcing work together to weaken the ambient stratification and to cause surface waters to sink to great depths wit...
Intensity of convective motions in marine atmospheric boundary layer retrieved from ocean surface radar imagery
Intensity of convective motions marine atmospheric boundary layer ocean surface radar imagery
2009/11/9
The paper focuses on the occurrence and development of coherent structures observed in the atmosphere above ocean under natural conditions. Microwave imaging radars are suggested as data take instrume...
Ideal-Fluid Thermocline with Weakly Convective Adjustment in a Subpolar Basin
Fluid Thermocline Convective Adjustment Subpolar Basin
2009/1/5
The ideal-fluid thermocline with continuous stratification is extended to include a weakly convective adjustment process taking place in a subpolar basin. The convective adjustment creates a well-mixe...
Convective flow in baroclinic vortices is studied analytically, taking viscosity ν, and thermal diffusivity κ into account. The meridional circulation depends strongly on the Prandtl number Pr = ν/κ. ...
Interdecadal Thermohaline Oscillations in a Sector Ocean General Circulation Model：Advective and Convective Processes
Interdecadal Thermohaline Oscillations zonal wind stress Ocean General Circulation Model surface freshwater flux
2008/12/12
Oceanic interdecadal thermohaline oscillations are investigated with a coarse-resolution version of the Geophysical Fluid Dynamics Laboratory Modular Ocean Model. The geometry of the model is a box wi...
Three-Dimensional Observations of a Deep Convective Chimney in the Greenland Sea during Winter 1988/89

Convective Regions energy transformations convective plumes
2008/12/10
An initially resting ocean of stratification N is considered, subject to buoyancy loss at its surface of magnitude B0 over a circular region of radius r, at a latitude where the Coriolis parameter is ...

Modeling Convective Transitions Sea lce deep-water formation mixed boundary conditions
2008/12/10
A substantial part of the variability in the thermohaline circulation on decadal and longer timescales as found in ocean models is strongly related to the deep-water formation (DWF) process. Many of t...
Effects of Rotation on Convective Plumes from Line Segment Sources
three-dimensional nonhydrostatic numerical model Line Segment Sources Convective Plumes
2008/12/10
Effects of rotation on finite-length line plumes are studied with a three-dimensional nonhydrostatic numerical model. Geophysical convection with this source geometry occurs, for example, as the resul...

Thermohaline Excitability flip–flop model
2008/12/9
Welander's flip–flop model exhibits oscillations when forced by stochastic white noise (with zero mean) even in the region of parameters where the deterministic system has a globally stable fixed poin...
