The water mass found north of the North Pacific subtropical convergence region between 50°N and the Alaskan coast. It has a temperature of 2°–6°C and a salinity below 33 psu.
Industry:Weather
The water mass of the subantarctic zone. It has a temperature of 4°–10°C in winter (August) and 4°–14°C in summer (January) and a salinity of 33. 9–34. 9 psu in winter, which can decrease to 33. 0 in summer from the melting of ice.
Industry:Weather
The water of the seas, distinguished from freshwater by its appreciable salinity. The distinction in usage of saltwater and seawater is not very sharply drawn. Commonly, seawater is used as the antithesis of specific types of freshwater, as river water, lake water, rainwater, etc. , whereas saltwater is merely the antithesis of freshwater in general.
Industry:Weather
The water that reaches streams (ranging from the large permanent streams to the tiny rills and rivulets that carry water only during rains) by traveling over the surface of the soil. Thus, surface runoff takes place only over the relatively short distance to the nearest minor channel. See overland flow.
Industry:Weather
The water, derived from precipitation, that ultimately reaches stream channels.
Industry:Weather
The wave activity occurring on a beach inshore of the point at which incoming waves break. Generally, surf consists of waves that have broken and therefore have air to some degree mixed in with the water.
Industry:Weather
The west wind in the Strait of Gibraltar. See mountain-gap wind, liberator; Compare ponente.
Industry:Weather
The wind measured at a surface observing station. This wind is customarily measured at a standard distance above the ground to minimize the distorting effects of local obstacles and terrain. See anemometer, wind vane, instrument exposure, winds aloft.
Industry:Weather
The writing component of a recording instrument. It is frequently located at some distance from the sensing portion of the instrument. See multiple register.
