Polyphony of Short-Term Climatic Variations
Atmosphere, 2021 It is widely accepted to believe that humanity is mainly responsible for the worldwide temperature growth during the period of instrumental meteorological observations. This paper aims to demonstrate that it is not so simple.

Geophysical Research Letters, Volume 50, Issue 12, 28 June 2023., 2023 Abstract Climate model estimates show significant groundwater depletion during the 20th century, consistent with global mean sea level (GMSL) budget analysis. However, prior to the Argo float era, in the early 2000’s, there is little information about steric sea level contributions to GMSL, making the role of groundwater depletion in this period less ...

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

Anthropause environmentalisms: Noticing natures with the Self‐Isolating Bird Club
Transactions of the Institute of British Geographers, Volume 48, Issue 2, Page 232-248, June 2023., 2023 Short Abstract This paper offers a detailed empirical account of how human‐environment relations were reconfigured in the UK and Ireland during the 2020–2021 COVID‐19 lockdowns, a period which natural scientists defined as the COVID‐19 Anthropause. Bringing this scientific concept into conversation with geographical work, we consider anthropause as ...

Chandler wobble excitation by catastrophic flooding of the Black Sea
Annals of Geophysics, 1999 It is now widely accepted that during the late Quaternary glaciation the Black Sea formed an isolated inland lake (Ross et al., 1970). New geological data and the recognition of sudden population movements away from the Black Sea coasts suggest that the ...

On Two Formulations of Polar Motion and Identification of Its Sources
Geosciences, 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.

Chandler Wobble and Free Core Nutation: Theory and Features
Journal of Astronomy and Space Sciences, 2019 Being a torque free motion of the rotating Earth, Chandler wobble is the major component in the Earth’s polar motion with amplitude about 0.05-0.2 arcsec and period about 430-435 days.

A possible interrelation between Earth rotation and climatic variability at decadal time-scale
Geodesy and Geodynamics, 2016 Using multichannel singular spectrum analysis (MSSA) we decomposed climatic time series into principal components, and compared them with Earth rotation parameters. The global warming trends were initially subtracted.

A preliminary nonlinear analysis of the earth's chandler wobble
Discrete 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.

Journal of Astronomy and Space SciencesTwo 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.
