The American Meteorological Society promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
The technique of determining the extinction characteristics of a medium by measuring the transmission of a light beam of known initial intensity directed into that medium.
Industry:Weather
The surface that separates the homosphere, in which the constituents of the atmosphere are well mixed by turbulence, from the heterosphere, in which constituents adopt their individual distributions with height as the result of molecular diffusion. The turbopause is not very clearly marked, but usually lies at a height of about 100 km, near the base of the thermosphere.
Industry:Weather
The ratio of weight of water transpired by a plant during its growing season to the weight of dry matter produced (usually exclusive of roots).
Industry:Weather
The side of a mountain, ridge, or other flow obstacle facing toward the direction of the large-scale or ridge-top wind; the upwind side; opposite of leeward.
Industry:Weather
The use of mathematical and/or numerical techniques to solve the equations describing the generation, interaction, propagation, and dissipation of waves on the ocean surface. The main types of wave modeling include 1) hydrodynamic modeling of fluid motions, to compute the evolution of the water surface and fluid velocities, and to compute forces on structures; 2) modeling of the propagation of waves as they approach the shore, taking account of refraction by varying depth; and 3) modeling of the evolution of the spectrum of the wave energy divided into components of different frequency and direction, in order to forecast the waves over an ocean region. Operationally, such models are used to produce wave forecasts (in much the same way as weather forecasts are produced) using wind information from meteorological forecast models.
Industry:Weather
The removal of solid and gaseous material from the air and its deposition on the earth's surface due to capture by falling precipitation.
Industry:Weather
The removal of atmospheric gases or particles through their incorporation into hydrometeors, which are then lost by precipitation. See deposition; Compare dry deposition.
Industry:Weather
The volume of water exchanged between a lagoon or estuary and the open sea in the course of a complete tidal cycle.
Industry:Weather
The two- or three-dimensional vector describing the instantaneous wind magnitude and direction at a point.
Industry:Weather
Used to describe nonuniform flow conditions in open channels and conduits, with changing cross section or slope with distance. When discharge is constant, the velocity changes with changes in slope and cross section. Relatively slow changes are known as gradually varied flow and are strongly influenced by surface resistance. Dramatic changes in velocity and depth occurring over a very short distance are known as rapidly varied flow and surface resistance effects are small.
