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, ...
A patch of white water formed at the crest of a wave as it breaks, due to air being mixed into the water. The formation of the whitecap dissipates energy from the wave. Whitecaps can persist after breaking has ceased, but slowly disappear as the air escapes from the water.
Industry:Weather
A numerical model with equations that accommodate the full range of dynamic modes of the hydrodynamic system being simulated. See filtered equations.
Industry:Weather
A name given by Sir Douglas Mawson (1915) to violent, snow-carrying whirlwinds, from a few to over one hundred meters in diameter, that occur in otherwise calm air on the slopes of Adélie Land, Antarctica, at about the time of the equinoxes. Over the sea, reportedly, they may lift brash 70–140 m into the air and form columns of water drops 1250 m high.
Industry:Weather
A northward flowing current that carries warm subtropical water into the East China Sea. It originates partly as an offshoot of the Kuroshio just northeast of Taiwan, partly as a current through Taiwan Strait. When it meets the southward flowing China Coastal Current near 30°S, it submerges and continues northward below a depth of 5 m.
Industry:Weather
A nonrecording rain gauge designed to be used at stations that can be visited only infrequently. The collection can may contain a solution with a low freezing point and a thin layer of oil to prevent evaporation. The amount of precipitation is found after subtracting the amount of solution.
Industry:Weather
A multivolume set of sailing directions published by the National Ocean Service that covers a wide variety of information important to navigators of U. S. Coastal and intracoastal waters, and waters of the Great Lakes. Most of this information cannot be shown graphically on the standard nautical charts and is not readily available elsewhere. This information includes navigation regulations, outstanding landmarks, channel and anchorage peculiarities, dangers, weather, ice, currents, and port facilities. Each Coast Pilot is corrected through Notices to Mariners issued subsequent to the date of original publication.
Industry:Weather
A narrow stream of air that transports large amounts of heat, moisture, and westerly momentum.
Industry:Weather
A model atmosphere used in numerical forecasting in which the parameters to be forecast are the height of one constant-pressure surface (usually 500 mb) and one temperature (usually the mean temperature between 1000 and 500 mb). Thus, a surface prognostic chart can also be constructed. The quasigeostrophic approximation is employed and the thermal wind is assumed constant with height.
Industry:Weather
A monsoon resulting from the circulation induced by temperature contrasts between a cold continent and a warm ocean as occurs during the winter season. An important example of this is the East Asian winter monsoon, which is the reversal of the East Asian summer monsoon.
