Ionospheric disturbances and gravity waves
Journal of Geophysical Research, 1976The response of ionization to a gravity wave moving through the ionosphere is studied. Hydrodynamic equations are used, and local thermodynamic equilibrium is imposed for simplicity. The treatment involves a perturbation analysis, and the background medium is assumed to be time stationary, horizontally stratified, and known. It is shown that ionization

The Effect of the Disturbing Potential for the Gravity Field
Solid State Phenomena, 2015The Earth’s gravity field tends to change due to various reasons. These are diverse processes occurring inside the Earth or changes initiated by human activity. The increasing accuracy of measurements has enabled to take into consideration fluctuations in the gravity field.

The theory of atmospheric disturbances induced by gravity field inhomogeneities
Doklady Earth Sciences, 2014Linear disturbances induced by gravity-field inhomogeneities in a horizontal stratified flow with a vertical shear are calculated analytically. In addition to being dependent on the amplitude of these inhomogeneities, disturbances depend strongly on their horizontal scales, background flow velocity, stratification, and Coriolis parameter.

The differences between gravity anomalies and gravity disturbances are numerically investigated in this study. In particular, we demonstrate how the topography, atmosphere and mass irregularities enclosed within the geoid contribute to these differences. The numerical analysis is conducted at the area of study in the Canadian Rocky Mountains.

On a rotational flow disturbed by gravity
Journal of Fluid Mechanics, 1976We examine a rapidly rotating flow that exhibits periodic vortex detachment. Specifically, the rotation/symmetry axis of a fluid-filled cylinder is set perpendicular to gravity. A free buoyant cylindrical float placed within the container is acted upon by both centrifugal and gravitational forces, the competition of which causes fluid motion and, in ...

Upward continuation of gravity disturbance covariance functions
Journal of Geophysical Research: Solid Earth, 1978One‐ and two‐dimensional integrals are derived for upward continuation of gravity disturbance covariance functions. Both spherical earth and flat earth formulas are presented as well as the associated Legendre and Fourier transforms.

On the boundary condition of the gravity disturbing potential
Studia Geophysica et Geodaetica, 1973The boundary condition for the gravity disturbing potential was derived upto the second-order terms and the influence of the second-order terms was investigated.

On gravity‐capillary waves due to interface disturbance
International Journal of Mathematical Education in Science and Technology, 1997The generation of gravity‐capillary waves at the interface between two superposed fluids due to interface disturbance is considered, assuming linear theory. Fourier and Laplace transform techniques are employed in the mathematical analysis and the form of the interface depression is obtained as an infinite integral involving oscillatory functions when ...

Journal of Geodesy, 2003
The geoid gradient over the Darling Fault in Western Australia is extremely high, rising by as much as 38 cm over only 2 km. This poses problems for gravimetric-only geoid models of the area, whose frequency content is limited by the spatial distribution of the gravity data.
