Effects of the Earth’s Irregular Rotation on the Moon-Based Synthetic Aperture Radar Imaging

open access: yesIEEE Access, 2019
The Moon-based Synthetic Aperture Radar (SAR) offers an exceptionally wide spatial coverage and short revisit time for the Earth observation. However, the complex imaging geometry in Moon-based SAR-Earth's target motion, where both the Earth's rotation ...

Some fresh indications of the solar origin of 4-6-year oscillation of the Earth’s rotation parameters [PDF]

open access: yesSerbian Astronomical Journal, 1999
The variations of universal times difference UT1-TAI and Earth’s rotation instantaneous pôle coordinates (X,Y) are studied in the frequency range of 3 - 8 yr−1 as a function of the solar activity.

SYNCHRONIZATION OF TERRESTRIAL PROCESSES WITH FREQUENCIES OF THE EARTH-MOON-SUN SYSTEM

open access: yesOdessa Astronomical Publications, 2016
It is established that the frequencies of the quasi-biennial oscillation (QBO) of atmospheric winds and the Chandler wobble (CW) of the Earth's poles are synchronized with each other and with the fundamental frequencies of the Earth–Moon–Sun system.

Gravitational Constraints on the Earth's Inner Core Differential Rotation

open access: yesGeophysical Research Letters, 2023
The differential axial rotation of the solid inner core (IC) is suggested by seismic observations and expected from core dynamics models. A rotation of the IC by an angle α takes its degree 2, order 2 topography (peak‐to‐peak amplitude δh) out of its ...

Influence of the horizontal component of Earth’s rotation on wind turbine wakes

open access: yesJournal of Physics: Conference Series, 2018
Wind turbines with large rotor diameters create wakes which are affected by the rotation of the earth. Aside from creating horizontal mean velocity veer, the Coriolis force, caused by earth’s rotation, also results in wake deflection and turbulence ...

Tectonic plates moment of inertia and angular momentum determination: the case of the Antarctic plate

open access: yesУкраїнський антарктичний журнал, 2023
The main goal of this study is to develop and test an algorithm for determining the moment of inertia and angular momentum of a tectonic plate based on the processing of time series of daily solutions of continuous GNSS (Global Navigation Satellite ...

A Novel Approach to Fully Nonlinear Mathematical Modeling of ‎Tectonic Plates [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2023
The motion of the Earth's layers due to internal pressures is simulated in this research with an efficient mathematical model. The Earth, which revolves around its axis of rotation and is under internal pressure, will change the shape and displacement of

Anomalies identification of Earth's rotation rate time series (2012–2017) for possible correlation with strong earthquakes occurrence

open access: yesGeodesy and Geodynamics, 2019
The analysis of the Earth's rotation rate time series, from January 1,2012 till December 31,2017, is performed using two different time series analysis methods, both based on signal decomposition joined with forecasting approach.
