Atmospheric Circulation of Brown Dwarfs: Jets, Vortices, and Time Variability [PDF]

, 2014
A variety of observational evidence demonstrates that brown dwarfs exhibit active atmospheric circulations. In this study we use a shallow-water model to investigate the global atmospheric dynamics in the stratified layer overlying the convective zone on

Compilation of the regional quasigeoid model for New Zealand using the discretised integral-equation approach

Journal of Geodetic Science, 2012
We evaluate the new regional quasigeoid model (OTG12) for New Zealand using the method which utilises the discretised integral equation approach for computing the near-zone contribution.

Towards the Selection of an Optimal Global Geopotential Model for the Computation of the Long-Wavelength Contribution: A Case Study of Ghana

, 2017
The selection of a global geopotential model (GGM) for modeling the long-wavelength for geoid computation is imperative not only because of the plethora of GGMs available but more importantly because it influences the accuracy of a geoid model.

A regional Stokes-Helmert geoid determination for Costa Rica (GCR-RSH-2020): computation and evaluation

Contributions to Geophysics and Geodesy, 2020
GNSS observations are a common solution for outdoor positioning around the world for coarse and precise applications. However, GNSS produces geodetic heights, which are not physically meaningful, limiting their functionality in many engineering ...

Polar mesoscale cyclones in the northeast Atlantic: Comparing climatologies from ERA-40 and satellite imagery [PDF]

, 2006
Polar mesoscale cyclones over the subarctic are thought to be an important component of the coupled atmosphere–ocean climate system. However, the relatively small scale of these features presents some concern as to their representation in the ...

Analysis of a Relative Offset between the North American and the Global Vertical Datum in Gravity Potential Space

Remote Sensing, 2023
The accurate estimation of the zero-height geopotential level in a local vertical datum (LVD) is critical for linking traditional height reference systems to a global height system.

A Comparison of Two Shallow Water Models with Non-Conforming Adaptive Grids: classical tests [PDF]

, 2007
In an effort to study the applicability of adaptive mesh refinement (AMR) techniques to atmospheric models an interpolation-based spectral element shallow water model on a cubed-sphere grid is compared to a block-structured finite volume method in ...

Geoid-to-Quasigeoid Separation Computed Using the GRACE/GOCE Global Geopotential Model GOCO02S - A Case Study of Himalayas and Tibet

, 2013
The geoid-to-quasigeoid correction has been traditionally computed approximately as a function of the planar Bouguer gravity anomaly and the topographic height.

Intercomparison of the northern hemisphere winter mid-latitude atmospheric variability of the IPCC models

, 2006
We compare, for the overlapping time frame 1962-2000, the estimate of the northern hemisphere (NH) mid-latitude winter atmospheric variability within the XX century simulations of 17 global climate models (GCMs) included in the IPCC-4AR with the NCEP and
