DegradationIn hydrologic terms, the geologic process by means of which various parts of the surface of the earth are worn down and carried away and their
general level lowered, by the action of wind and water.GRADGradient- A rate of change with respect to distance of a variable quantity, as temperature or pressure, in the direction of maximum change.Gradient(abbrev. GRAD) A rate of change with respect to distance of a variable quantity, as temperature or pressure, in the direction of maximum change.Gradient High WindsThese high winds usually cover a large area and are due to synoptic-scale, extra-tropical low pressure systems.Gradual CommencementIn solar-terrestrial terms, the commencement of a geomagnetic storm that has
no well-defined onsetHydraulic Grade LineIn hydrologic terms, a line whose plotted ordinate position represents the sum of pressure head plus elevation head for the various positions along a
given fluid flow path, such as along a pipeline or a ground water streamline.Pressure GradientThe amount of pressure change occurring over a given distance.Pressure Gradient ForceA three-dimensional force vector operating in the atmosphere that accelerates air parcels away from regions of high pressure and toward regions of low pressure in response to an air pressure gradient. Usually resolved into vertical and horizontal components.
