By analogy with Poincare waves in a channel, these are inertio-gravity waves confined to a region about the equator. The meridional velocity of the n'th mode of these waves has meridional structure of the form exp(-y^2/2R^2) H_n(y/R), in which y is the meridional distance from the equator, R is the equatorial Rossby deformation radius, and H_n is the n'th Hermite polynomial. In the shallow water approximation R^2=(gH)^(1/2)/\beta in which, \beta is the meridional gradient of the Coriolis parameter at the equator, g is the acceleration of gravity, and H is the mean fluid depth. The dispersion relation for the n'th mode (n>0) with zonal wavenumber k is given by those roots of the equation, cubic in frequency \omega, ((gH)^(1/2)/\beta) (-k\beta/\omega - k^2 + \omega^2/(gH)) =2n+1 for which the frequency exceeds R\beta.

Change of a substance to a denser form such as gas to a liquid. The opposite of evaporation.
Industry:Earth science
Changes in the sea level relative to that of the land, which operates on a regional/local level. It can be brought about by a change in sea level and/or a change in the level of the land.
Industry:Earth science
Common gas found in the atmosphere. Has the ability to selectively absorb radiation in the longwave band. This absorption causes the greenhouse effect. The concentration of this gas has been steadily increasing in the atmosphere over the last three centuries due to the burning of fossil fuels, deforestation, and land-use change. Some scientists believe higher concentrations of carbon dioxide and other greenhouse gases will result in an enhancement of the greenhouse effect and global warming. The chemical formula for carbon dioxide is CO2.
Industry:Earth science
Consisting of parallel bands, layers, or sheets. Used to describe clouds of extensive horizontal rather than vertical development.
Industry:Earth science
Cracks in the ocean floor that emit jets of hot water loaded with minerals and bacteria. The vents range in diameter from less than an inch to mare than six feet. They are usually found at least a mile deep long the mid-ocean ridges. So far, several dozen vent fields have been discovered.
Industry:Earth science
Currents associated with the cyclical rise and fall of the water level as described in the definition of tide.
Industry:Earth science
Denotes how fluid motion is affected by spatial changes of the Coriolis parameter, for example, due to the Earth's curvature. The term takes its name from the symbol \beta, representing the meridional gradient of the Coriolis parameter at a fixed latitude. A linearly sloping lower boundary to fluid in a rotating system also experiences the beta effect.
