reduced gravity
Earth science; Oceanography
The effective change in the acceleration of gravity acting on one fluid in contact with a fluid of different density due to buoyancy forces. Explicitly, the reduced gravity is ...
heat flux
Earth science; Oceanography
The flow of heat across a surface of unit area in a unit amount of time; commonly expressed in units of cal/cm2-sec or W/(M2-A).
pressure gradient force
Earth science; Oceanography
The force that causes acceleration from higher to lower pressure in a fluid such as the air. It arises because of a pressure gradient or change between higher and lower pressure. ...
cardinal points
Earth science; Oceanography
The four main navigational directions (North, East, South, and West) found on a compass or a map.
power spectrum
Earth science; Oceanography
The Fourier transform of the kinetic energy field. The power spectrum provides a useful diagnostic to measure a what length scales energy is concentrated and, in turbulent flow, ...
oceanic conveyor belt
Earth science; Oceanography
The global oceanic conveyer belt, is a unifying concept that connects the ocean's surface and thermohaline (deep mass) circulation regimes, transporting heat and salt on a ...
greenhouse effect
Earth science; Oceanography
The greenhouse effect causes the atmosphere to trap more heat energy at the Earth's surface and within the atmosphere by absorbing and re-emitting longwave energy. Of the ...
