A popular nautical term for the stormy ocean regions between 40 degreesand 50 degreeslatitude. It nearly always refers to the southern hemisphere, where there is an almost completely uninterrupted belt of ocean with strong prevailing westerly winds.
Industry:Earth science
A strip of land that juts seaward from the coastline. This feature normally bordered by a cliff.
Industry:Earth science
An approximation, useful for the study of equatorial and midlatitude flow, whereby the Coriolis parameter is taken to vary linearly with latitude. Explicitly, the Coriolis parameter is given approximately by f \simeq f_0 + \beta y in which y is the meridional distance from some fixed latitude where the Coriolis parameter is f_0, and \beta (from which the ``beta plane'' gets its name) is the meridional gradient of f at that fixed latitude.
Industry:Earth science
The ocean current with the largest volume transport (approximately 110 x 10(s) m(s)/sec), and the swiftest current; it flows from west to east through all the oceans around the Antarctic Continent. It is locally deflected from its course, partly by the distribution of land and sea and partly by the submarine topography. Beside the bends that are associated with the bottom topography, the effects of the distribution of land and sea and of the currents in the adjacent oceans are also evident. On its northern edge it is continuous with the South Atlantic current , the South Pacific current and the eastward-flowing extension of the Agulhas current in the Indian Ocean. A flow to the west near the Antarctic Continent is evident only in the Weddell Sea area, where an extensive cyclonic motion occurs to the south of the circumpolar current. antarctic convergence.
Industry:Earth science
An imaging system consisting of lenses, moving mirrors, and solid-state image sensors used to obtain observations of Earth and its atmosphere. Scanning radiometers, which are the sole imaging systems on all current operational weather satellites, have far better long-term performance than the vidicon TV camera tubes used with earlier spacecraft.
Industry:Earth science
A branch of geology concerned with the surface features of the Earth, including landforms and forms under the oceans, and the chemical, physical and biological factors that act on them.
Industry:Earth science
A strip of relatively flat and normally dry land alongside a stream, river, or lake that is covered by water during a flood.
Industry:Earth science
A property of a material, measured as the emittance of a specimen of the material that is thick enough to be completely opaque and has an optically smooth surface.
Industry:Earth science
A horizontal movement of water in a well-defined, established pattern, as in a river or stream. The movement of a definite body of air in a certain direction.
