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, ...
Tidal waves that propagate at density differences within the ocean. They travel slowly compared with surface gravity waves and have wavelengths of only a few tens of kilometers, but they can have amplitudes of tens of meters. The associated internal currents are termed baroclinic motions.
Industry:Weather
The water, derived from precipitation, that infiltrates the soil surface and then moves laterally through the upper layers of soil above the water table until it reaches a stream channel or returns to the surface at some point downslope from its point of infiltration. Although readily defined, interflow is difficult to measure and quantify. Compare subsurface flow.
Industry:Weather
The water portion of the earth as distinguished from the solid part, called the lithosphere, and from the gaseous outer envelope, called the atmosphere. The hydrosphere includes snow, ice, and glaciers. Sometimes the water in the atmosphere, which includes water vapor, clouds, and all forms of precipitation while still in the atmosphere, is included in the term hydrosphere. See also biosphere, geosphere.
Industry:Weather
The use of interference phenomena for purposes of measurement. In radar, one use of interferometric techniques is to determine the angle of arrival of a wave by comparing the phases of the signals received at separate antennas or at separate points on the same antenna. Another interferometric application is to shape and steer the beams of phased- array antennas by adjusting the phases of the different elements of the array.
Industry:Weather
The water entering into an aquifer from a stream or body of water as a result of lowering the water table or potentiometric head in an aquifer.
Industry:Weather
The use of automated or manual techniques to provide the means of assessing, preprocessing, extracting features, classifying, identifying, and displaying the original or processed imagery for subjective evaluation, interpretation, and further interaction with the data.
Industry:Weather
The traditional technique for measuring the properties of the ionosphere by transmission and reception of vertically incident radio pulses at swept frequencies in the HF range.
Industry:Weather
The transducer of any hygrometer, that is, that part of a hygrometer that quantitatively “senses” atmospheric water vapor.
Industry:Weather
The transport of upper ocean water from the Pacific to the Indian Ocean through the Indonesian Seas. The throughflow is an important link in the ocean conveyor belt. It is driven by the sea level difference between the Pacific and Indian Oceans and is at its maximum, with 12–20 Sv (12–20 × 106 m3 s−1), during May–September, when it opposes the wind. The minimum, 2–5 Sv, occurs during November–March, when it follows the wind.
