Ocean General Circulation Model¶
Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans.
Core Idea¶
Ocean General Circulation Model is treated here as the recurring natural science, engineering, and health identity summarized by this source-grounded definition: Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans. Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans. The oceanic general circulation is defined as the horizontal space scale and time scale larger than mesoscale (of order 100 km and 6 months).
Scope of Application¶
-
Classification. Idealized geometry models: Models with idealized basin geometry have been used extensively in ocean modeling and have played a major role in the development of new modeling methodologies.
-
History. The first application with specified global geometry was done in the early 1970s.
-
History. Furthermore, in order to predict tidal effects or compare height data from satellites, methods were developed to predict the height and pressure of the ocean surface directly.
-
History. For example, one method is to treat the free surface and the vertically averaged velocity using many small steps in time for each single step of the full 3D model.
-
History. Another method developed at Los Alamos National Laboratory solves the same 2D equations using an implicit method for the free surface.
Clarity¶
A clear use of Ocean General Circulation Model names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans.
Manages Complexity¶
Ocean General Circulation Model compresses multiple natural science, engineering, and health details into a stable diagnostic relation. The source shows both the central mechanism—the speed at which this equilibrium is reached is determined by slow processes below the thermocline.—and the practical consequence—the big advantage of finite element grids is that it allows flexible resolution throughout the domain of the model.
Abstract Reasoning¶
- Type the carrier. Identify the natural science, engineering, and health entities to which the claim applies.
- State the relation. Use the source-grounded identity: Ocean general circulation models (OGCMs) are a particular kind of general circulation model to describe physical and thermodynamical processes in oceans.
- Check operation and conditions. The acceleration of these processes is achieved by decreasing the local heat capacity, while not changing the transport and the mixing of heat.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Ocean General Circulation Model transfers literally when a new case preserves the same carrier type, relation, and recognition test. Idealized geometry models: Models with idealized basin geometry have been used extensively in ocean modeling and have played a major role in the development of new modeling methodologies. The first application with specified global geometry was done in the early 1970s. Beyond the home domain. No canonical parent is asserted for Ocean General Circulation Model.
