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. ...

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

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...
