Analysis of the Chandler Period of Polar Coordinates Calculated by the Orlov Method [PDF]

open access: yesSymposium - International Astronomical Union, 1972
The coordinates x and y of the pole related to mean pole of the epoch in the period 1900–1962 for the ILS station were calculated utilising the method proposed by Orlov (1955). The values of the latitudes are those reduced in the homogeneous system of Carnera-Cecchini by Proverbio et al. (1969).

The numerical prediction of the Earth’s polar motion based on an advanced multivariate algorithm

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Since there are complicated changes in the polar motion (PM) from sub-annual to decadal, precisely predicting it is challenging. Here, we provide an advanced multivariate algorithm by combining an iterative oblique singular spectrum analysis (IOSSA) with

Assessment of apparent nonstationarity in time series of annual inflow, daily precipitation, and atmospheric circulation indices: A case study from southwest Western Australia [PDF]

open access: yes, 2010
The southwest region of Western Australia has experienced a sustained sequence of low annual inflows to major water supply dams over the past 30 years. Until recently, the dominant interpretation of this phenomenon has been predicated on the existence of

A preliminary nonlinear analysis of the earth's chandler wobble

open access: yesDiscrete Dynamics in Nature and Society, 2000
The Chandler wobble (CW) is a resonant response of the Earth rotational pole wandering around its figure axis whose excitation mechanism is still uncertain.

On Two Formulations of Polar Motion and Identification of Its Sources

open access: yesGeosciences, 2022
Differences in formulation of the equations of celestial mechanics may result in differences in interpretation. This paper focuses on the Liouville-Euler system of differential equations as first discussed by Laplace.

Performance of Strawberry Varieties Developed for Perennial Matted-Row Production in Annual Plasticulture in a Cold Climate Region

open access: yesAgronomy, 2021
Annual plasticulture production of strawberries promises superior weed control, fruit quality and yields. However, strawberry varieties adapted for perennial, matted-row production and local markets in cold climate regions have not been widely tested for

Chandler period estimated from frequency domain expression solving the Liouville equation for polar motion

open access: yesGeophysical Journal International, 2022
SUMMARYAccurate determination of the Chandler wobble (CW) period (TCW) and quality factor (QCW) is of great significance to our understanding of the Earth's dynamic figure parameters, elasticity, rheology and energy dissipation. TCW and QCW were typically determined in the time domain using the digital filter designed by Wilson; however, we developed ...

Main Oscillatory Polar Motion of the Earth and Its Excitation: Investigation in Both the Frequency and Time Domains

open access: yesJournal of Astronomy and Space Sciences
Two main components of polar motion are Chandler wobble and annual wobble. Annual wobble is obviously caused by the seasonal perturbations on the Earth – such was suspected as well as readily confirmed in unison.
