Total rainfall intercepted before reaching ground surface or open water body.
Industry:Weather
Time interval between the beginning of a wind gust and the gust peak wind speed.
Industry:Weather
Time as considered in terms of the history of the earth. It is divided into geologic eras, periods, and epochs. Depending on the part of the geologic time scale, increments are as long as tens of millions of years or as short as hundreds of years. In general, geologic time is more finely divided closer to the present.
Industry:Weather
Those tropospheric winds that carry radioactive fallout materials (primarily materials produced by atmospheric tests of nuclear weapons). These winds are observed by standard winds-aloft observation techniques. Fallout winds are used to construct radioactive fallout plots and ground fallout plots.
Industry:Weather
Theory of the formation and development of air masses, cold fronts, and warm fronts in the atmosphere, and of the formation and development of extratropical depressions in relation to air masses and fronts.
Industry:Weather
The western boundary current of the North Atlantic subtropical gyre and its eastward continuation, consisting of the Florida Current, the Gulf Stream, the Gulf Stream Extension, and its continuation in the North Atlantic and Azores Currents.
Industry:Weather
The vertical distance between normal maximum operating level at a reservoir and the top of the dam, or between the design flood stage and the top of a levee. Adequate free-board is employed as a safety interval and provides protection against overtopping by wave action, debris, etc.
Industry:Weather
The volume of fluid passing through a unit area perpendicular to the direction of flow in a unit of time.
Industry:Weather
The water exuded from leaves as a result of root pressure. Sometimes guttation is confused with dew, although the origin and appearance of the resulting drops are different. On grass, dew appears as many drops that cover the surface of the blade; dew forms by condensation from water vapor in the atmosphere. Guttation appears as a single large pendant drop at the tip of the blade; guttation forms by the extrusion of liquid water from the moist ground. Sometimes one is seen, sometimes the other, sometimes both. When a wet heiligenschein is seen on the grass it is mainly caused by dewdrops; when a rainbow is seen on the grass it is mainly caused by guttation drops. See also dewbow.
Industry:Weather
The upward or outward movement of the ground surface (or objects on, or in, the ground) caused by the formation of ice in the soil. (Glossary of Permafrost and Related Ground-Ice Terms, National Research Council of Canada, NRCC 27952, Technical Memorandum No. 142, 1988. )
