Geopotential Height height of a given pressure
Geopotential height approximates the actual height of a pressure surface above mean sea-level.
Geopotential height
Geopotential height approximates the actual (gravity-weighted) height of a pressure level above mean sea-level.
Geostrophic wind ...
Geopotential Height- approximates the actual height of a pressure surface above mean sea-level in meters. For example a geopotential height of 1500 is the number of meters above sea-level one would have to be to reach a pressure of 850mb.
Geopotential height
The altitude of a layer in the atmosphere. It is used to define isobaric surfaces on upper level charts.
Geostrophic wind ...
Geopotential Height
The height above sea level of a pressure level.
are geopotential height fields with
φ1 > φ0
,
f
is the Coriolis parameter, and is the upward-pointing unit vector in the vertical direction. The thermal wind equation does not determine the wind in the tropics.
HeightIn meteorology, usually a reference to Geopotential Height; roughly the height above sea level of a pressure level.
It is directed normal to sea level and to its geopotential surfaces. The magnitude of the force of gravity at sea level decreases from the poles, where the centrifugal force is zero, to the equator, ...
In meteorology, the force of gravity has a potential, the geopotential, which, if the acceleration of gravity g is taken as constant, may be written φ = gZ, where Z is the height coordinate.
geopotential heightGravity-weighted height of a pressure surface, usually in a model that uses pressure as the vertical coordinate.
ISOHYPSE- A line of constant geopotential height (height contour).
ISOPLETH- A line of a constant meteorological value.
ISOSTER- A line of a constant density.
Gradient wind Any horizontal wind velocity tangent to the contour line of a constant pressure surface (or to the isobar of a geopotential surface) at the point in question. Gradient wind level Same as geostrophic wind level. Gram A c.g.s.
