Horizontal Ocean Circulation Forced by Deep-Water Formation. Part II：A Quasi-geostrophic Simulation
A Quasi-geostrophic Simulation Deep-Water Formation Horizontal Ocean Circulation
2009/1/5
This numerical experiment aims to investigate the dynamical effects of the vertical convection of waters, occurring in regions where the cooling of the upper ocean is due to periodical, local, rough w...
Horizontal Ocean Circulation Forced by Deep-Water Formation. Part I：An Analytical Study
Horizontal Ocean Circulation Deep-Water Formation Analytical Study
2009/1/5
The horizontal ocean circulation generated by vertical convection is investigated analytically. The stratification is parameterized by a two-layer ocean and attention is focused on the spinup phase wh...

North Atlantic Deep Water Antarctic Bottom Water Ocean Deep-Water Circulation
2008/12/23
A multilayer ocean model that is physically simple and computationally efficient is developed for studies of competition and interaction among deep-water sources in determining ocean circulation. The ...
Variability and Multiple Equilibria of the Thermohaline Circulation Associated with Deep-Water Formation
Multiple Equilibria Deep-Water Formation Thermohaline Circulation
2008/12/16
In this study the variability of the thermohaline circulation on decadal and centennial time scales that is related to the process of deep-water formation is investigated. This is done within the cont...
Stability of North Atlantic Deep Water Formation in a Global Ocean General Circulation Model
North Atlantic Deep Water Formation Global Ocean General Circulation Model
2008/12/15
A global ocean general circulation model is forced using mixes boundary conditions (i.e., a restoring condition on the upper-level temperature but using a fixed, specified surface salt flux). Freshwat...
Stability Characteristics of Deep-Water Replacement in the Strait of Georgia
Stability Characteristics Deep-Water Replacement
2008/12/12
It has been suggested that low-frequency current fluctuations in the southern Strait of Georgia are the result of baroclinic instability. However, data extracted from cyclesonde and fixed current mete...
The Spreading of Lower Circumpolar Deep Water in the Atlantic Ocean
Lower Circumpolar Deep Water Atlantic Ocean Stommel-Arons model
2008/12/12
A Stommel-Arons model of the circulation of Lower Circumpolar Deep Water (LCDW) in the Atlantic Ocean is presented and compared with observations. The LCDW is defined as a layer of uniform thickness o...
