Association of geopotential height patterns with heavy rainfall events in Cyprus [PDF]
Advances in Geosciences, 2010 Dynamically induced rainfall is strongly connected with synoptic atmospheric circulation patterns at the upper levels. This study investigates the relationship between days of high precipitation volume events in the eastern Mediterranean and the ...

Rising geopotential height under global warming
Climate Dynamics, 2023 Abstract Geopotential height (H) is a widely used metric for atmospheric circulation. H has been reported to be rising under global warming, but the amplitude and mechanism of this rise are not clear. Based on reanalysis datasets and climate models participating in CMIP6, this study quantitatively evaluates the sensitivity of H to global mean ...

The Arctic oscillation signature in the wintertime geopotential height and temperature fields [PDF]
Geophysical Research Letters, 1998 The leading empirical orthogonal function of the wintertime sea‐level pressure field is more strongly coupled to surface air temperature fluctuations over the Eurasian continent than the North Atlantic Oscillation (NAO). It resembles the NAO in many respects; but its primary center of action covers more of the Arctic, giving it a more zonally symmetric

Global Geopotential Models assessment in Ecuador based on geoid heights and geopotential values
Journal of Geodetic Science, 2023 Since the 1960s, the analysis of disturbed satellite orbits to infer Earth’s gravity field functionals has been an important element in determining the Earth’s gravitational field. The long wavelengths of the gravitational field are recovered through the

Determination of the geopotential and orthometric height based on frequency shift equation [PDF]
Natural Science, 2011 The orthometric height (OH) system plays a key role in geodesy, and it has broad applications in various fields and activities. Based on general relativity theory (GRT), on an arbitrary equi-geo- potential surface, there does not exist the gravity ...

Teleconnections in the Geopotential Height Field during the Northern Hemisphere Winter
Monthly Weather Review, 1981 Contemporaneous correlations between geopotential heights on a given pressure surface at widely separated points on earth, referred to as teleconnections in this paper, are studied in an attempt to identify and document recurrent spatial patterns which ...

The Evaluation of Winds from Geopotential Height Data in the Stratosphere.
Journal of the Atmospheric Sciences, 1987 Several methods of obtaining horizontal wind fields in the extratropical stratosphere from geopotential height data are evaluated and compared to geostrophic estimates, with focus on the poleward fluxes of momentum and heat and on the resulting Eliassen ...

Connection between the large-scale 500 hPa geopotential height fields and precipitation over Greece during wintertime [PDF]
, 2000 The spatial distribution of the winter (December to February) precipitation over Greece was related to the eastern North Atlantic-European scale mid-tropospheric circulation fields by means of empirical orthogonal functions (EOFs) and canonical ...
