Recent variations in geopotential height associated with West African monsoon variability

Meteorology and Atmospheric Physics, 2018
In the present study, the atmospheric circulation patterns associated with the seasonal West Africa (WA) monsoon (WAM) rainfall variability has been investigated. The observational rainfall data from the Climatic Research Unit (CRU) and atmospheric fields from the National Center for Environmental Prediction (NCEP) reanalysis 2, from 1979 to 2014, have

Optimal determination of geopotential base height for stratospheric temperature sounders

pure and applied geophysics, 1980
A technique is developed for optimally determining a base geopotential field, on which stratospheric heights may be constructed from remotely sensed temperatures. The scheme employs height information from within as well as below remote observational levels.

Skewness, Kurtosis and Extreme Values of Northern Hemisphere Geopotential Heights

Monthly Weather Review, 1980
Abstract Twelve summers and 11 winters of Northern Hemisphere 500 and 1000 mb geopotential height are used to calculate the third and fourth moments of height in the nondimensional form of skewness and kurtosis. Geopotential height exhibits small but statistically significant departures from a normal distribution in places, especially in low latitudes.

World Height System Specified by Geopotential at Tide Gauge Stations

2002
World Height System (WHS) can be directly specified and practically realized within a Terrestrial Reference System (TRS) by choosing a geoidal geopotential W 0. There are two possible ways how to select the W 0of the WHS datum: (1) By adopting W 0 as the reference geopotential value, to which all the Local Vertical Datums (LVDs) should be ...

Linear Trends in Northern Hemisphere Tropospheric Geopotential Height and Temperature Patterns

Journal of the Atmospheric Sciences, 1982
Gridded National Meteorological Center data for 500 mb geopotential height and 300-500 mb and 500-700 mb thickness for the period 1951-1978 are subjected to linear trend analyses. The analyses are carried out for each calendar month. Significant geographical and seasonal distributions of cooling and warming patterns are found.

Which type of WNPSH indices can be better applied, defined by the geopotential height, the eddy geopotential height, or the stream function?

The western North Pacific subtropical high (WNPSH) is a crucial circulation system affecting weather and climate over China. To quantitatively measure its strength and spatial pattern, the geopotential height was firstly used to define WNSPH indices (H indices). However, due to global warming, the H indices have&#
