WebNov 14, 2024 · geopotential. The potential energy of a unit mass relative to sea level, numerically equal to the work that would be done in lifting the unit mass from sea level to the height at which the mass is located; commonly expressed in terms of dynamic height or geopotential height. The geopotential Φ at height z is given mathematically by the ... WebGeopotential height is valuable for locating troughs and ridges which are the upper level counterparts of surface cyclones and anticyclones. The primary characteristic of a trough is that it is a region with relatively lower …

WebJun 10, 2000 · Figure 7. Eta model initial analysis of absolute geostrophic vorticity … Geopotential height or geopotential altitude is a vertical coordinate referenced to Earth's mean sea level, an adjustment to geometric height (altitude above mean sea level) that accounts for the variation of gravity with latitude and altitude. Thus, it can be considered a "gravity-adjusted height". It is the altitude … See more Geophysical sciences such as meteorology often prefer to express the horizontal pressure gradient force as the gradient of geopotential along a constant-pressure surface, because then it has the properties of a See more • Media related to Geopotential height at Wikimedia Commons See more • Atmospheric model • Above mean sea level • Dynamic height See more • Hofmann-Wellenhof, B. and Moritz, H.
