Channel reach upstream of a gauging station or a control structure; the reach is chosen such that flow is uniform at the station.
Industry:Weather
A field of study where weather data, analyses, and forecasts are put to practical use. Examples of applications include environmental health, weather modification, air pollution meteorology, agricultural and forest meteorology, transportation, value-added product development and display, and all aspects of industrial meteorology. Compare applied climatology.
Industry:Weather
Branch of hydrology associated with the practical use of the science to solve technical problems.
Industry:Weather
The scientific analysis of climatic data in the light of a useful application for an operational purpose. “Operational” is interpreted as any specialized endeavor within such as industrial, manufacturing, agricultural, or technological pursuits (after Landsberg and Jacobs 1951). This is the general term for all such work and includes agricultural climatology, aviation climatology, bioclimatology, industrial climatology, and others.
Industry:Weather
The first experimental geostationary satellite series, operated by NASA, that preceded the SMS and GOES series. ATS-1, launched in December 1966, carried the first spin scan cloud camera, providing full- disk visible imagery every 30 minutes, and introduced WEFAX data relay.
Industry:Weather
A process that has the same effect as a stress. An example is the Reynolds stress, where turbulent motions can exchange fluid from within a hypothetical cube of air with fluid of different velocity from outside the cube, causing the cube to deform in a manner similar to a stress acting on the face of the cube.
Industry:Weather
The interval of time between two successive transits of the sun across a meridian. This interval is about four minutes longer than the sidereal day, largely because of the sun's apparent annual motion eastward along the ecliptic (actually, the earth's “westward” motion along its orbit), which motion delays the sun's return to meridional transit. Also, this interval is inconveniently nonuniform due to systematic variations in the earth's orbital speed around the sun and the sun's changing declination. The concept of the mean solar day has been invented to circumvent these practical difficulties.
Industry:Weather
The volume of groundwater passing through a unit area of porous medium, perpendicular to the direction of flow, in a unit of time.
Industry:Weather
The line between the sky and the earth projected on the celestial sphere. This line is often irregular, due to the earth's topography. On flat surfaces, such as the sea or a level plane, the line approximates a great circle if the observer's elevation above the surface is insignificant and a small circle if the elevation is appreciable.
