One practical use of the decameter is for altitude of geopotential heights in meteorology.
2.
The geopotential surface called the geoid is one definition of the shape of the Earth.
3.
Levelling instruments again are used to obtain geopotential differences between points on the Earth's surface.
4.
Geopotential surface heights above the 1000 dB level, computed using historical data, show only very weak surface currents.
5.
A more convenient unit is the GPU, or geopotential unit : it equals 10 m 2 �s " 2.
6.
Furthermore, the velocity, temperature, and geopotential variables may be decomposed into mean and perturbation components using Reynolds decomposition.
7.
It uses geopotential, specific heat, the exner function " ? ", and change in sigma coordinate.
8.
Note that the Lapse Rates cited in the table are given as �C per kilometer of geopotential altitude, not geometric altitude.
9.
The cold air will be denser . . . but that means its geopotential height for any given pressure will be shorter.
10.
For the purpose of satellite orbital mechanics, the geopotential is typically described by a series expansion into spherical harmonics ( spectral representation ).
