AbstractGeopotential height data at 500hPa level in recent 50 years is used to investigate the evolutive laws of Antarctic, Equatorial and Arctic geopotential heights, zonal wind, and the correlation between one and another. Results show that Antarctic (Equatorial) geopotential height descends (ascends) evidently.

Monitoring the Madden–Julian oscillation with geopotential height
Climate Dynamics, 2016This paper examines the three-dimensional geopotential height structure of the Madden–Julian oscillation (MJO) and proposes that the MJO convection signals can be well reflected by upper-tropospheric zonal anomalous height gradient (ZAHG, $$\nabla_{x} z'$$

On the Interpretation of Geopotential Height Tendency Equations
Monthly Weather Review, 1993Abstract The conceptual model for height tendency presented by Hirschberg and Fritsch directly links upper-level virtual temperature tendency with low-level height tendency, overlooking the essential dynamics of mass divergence. An analysis of the complete height tendency equation shows that upper-level virtual temperature change car only indirectly ...

Autocorrelation of Northern Hemisphere Geopotential Heights
Monthly Weather Review, 1983Abstract Local autocorrelation statistics for the Northern Hemisphere geopotential height field are presented for different seasons and tropospheric pressure levels. Values are generally much higher than those calculated from time series of outgoing infrared radiation or eddy heat fluxes. The largest one-day lag autocorrelation values are observed over

Deriving orthometric height using global geopotential models (GGMs) [PDF]
2016 7th IEEE Control and System Graduate Research Colloquium (ICSGRC), 2016 The purpose of this paper is to evaluate the orthometric height derived by combination of Global Navigation Satellite System (GNSS) data and global geoid height information over Peninsular Malaysia. The global geoid height information is derived from recent Global Geopotential Models (GGMs); combined and satellite-only solution.

Chronometric Height: a relativistic height definition by generalizing geopotential numbers
2021<p>A height definition in terms of geopotential numbers offers a variety of advantages. Moreover, from the theoretical point of view, such a definition is considered more fundamental.&#160;</p><p>We know, however, that relativistic gravity (here General Relativity) requires to reformulate the basic ...

The influence of geopotential heights on New South Wales rainfall
Meteorology and Atmospheric Physics, 1997An investigation of the relationships between New South Wales (NSW) seasonal rainfalls and fluctuations of geopotential height at four Australian radiosonde stations is presented. The connection between the Southern Oscillation Index (SOI) and the geopotential height was explored up to the mid-troposphere.

The linkage between geopotential height and monthly precipitation in Iran
Theoretical and Applied Climatology, 2018This paper investigates the linkage between large-scale atmospheric circulation and monthly precipitation during November to April over Iran. Canonical correlation analysis (CCA) is used to set up the statistical linkage between the 850 hPa geopotential height large-scale circulation and monthly precipitation over Iran for the period 1968–2010.

Improved Skill for the Anomaly Correlation of Geopotential Heights at 500 hPa [PDF]
Monthly Weather Review, 2003 This paper addresses the anomaly correlation of the 500-hPa geopotential heights from a suite of global multimodels and from a model-weighted ensemble mean called the superensemble. This procedure follows a number of current studies on weather and seasonal climate forecasting that are being pursued.
