О ДВИЖЕНИЯХ ЛУНЫ КАК ВОЗМОЖНОМ КЛИМАТООБРАЗУЮЩЕМ ФАКТОРЕ
С. 41–48.
It is well known, that inclination of the Earth rotation axis to the ecliptic plain defines the maxima
and minima declination of the Sun on the days of solstices. According to the Milankovitch theory
variations of this parameter are one of the causes of the glacial periods. Some facts show, that motions
of the Moon from equator to the maxima declinations also influence the processes in the atmosphere
and ocean. The changes of maxima declinations of the Moon in the 18.6-year orbital precession cycle
could put important footprint on the Earth climate.
We discuss the results of analysis of the atmospheric angular momentum, pressures and winds,
Earth mean temperature, sea level changes, comparing them with the Earth rotation changes and moon
tidal effects.

Earth rotation in recent epoch shows anomalies: its rotation velocity reached decadal maximum in 2024; the Chandler wobble (CW) of the rotation axis disappeared in 2018–2020, then resumed with a phase changed by 180^\circ
◦; the ampli-tude of the Free Core Nutation (FCO) decreased since 2021 as well. We analyzed the CW amplitude modulations since the ...

It is shown that the 580-year eclipse cycle occurs due to the modulation of the cycle of Saros (18.03) with a cycle of precession of the plane of the lunar orbit (18.61). The addition of these two cycles gives rise to 580 cycles of eclipses of the moon and sun. A mathematical model of this ...

One of the major components of the Earth’s polar motion is Chandler wobble with 433-day period. To extract it from observations narrow-band filtering is required. We have developed method which joins Kalman filtering and band-pass filtering in direct time with the phase correction in reversed time. By using Euler-Liouville equation generating resonant CW as a ...

The GRACE and GRACE-FO satellites provide data on the Earth's gravitational field changes and are among the most successful NASA/DLR geodetic missions in recent decades. Based on their data, the melting of glaciers, redistribution of masses in the river basins, and changes in the ocean mass are studied. We use multichannel singular spectral analysis (MSSA) ...

Since strong El Nino 2016 the tendency of acceleration of the Earth rotation has been observed. In 2022 the Earth rotation velocity reached maxima comparable with those happened 90 years ago. Triplet of La Nina accompanied this case. Chandler wobble of the pole almost disappeared in 2017-2020, which was earlier observed only in the end ...

The Early 20th Century Warming (ETCW) in the northern high latitudes was comparable in magnitude to the present-day warming yet occurred at a time when the growth in atmospheric greenhouse gases was rising significantly less than in the last 40 years. The causes of ETCW remain a matter of debate. The key issue is to assess ...

The Earth’s rotation is nonuniform: the position of the pole drifts and describes circles with the annual and Chandler (433 days) periods; the Earth’s rotation velocity also varies. In the beginning of 2000s, the amplitude of the Chandler wobble began to decrease and in 2017–2020 reached a historical low comparable only with the low of ...

We analyzed the impacts of data span on trend estimates using Earth’s long-term polar motion time series, 1846-present, and using methodologies including singular spectrum analysis, and Panteleev’s filter to mitigate the time series containing transient signals. Our results show that the fluctuations of the mean rotational pole position, the Markowitz wobble, cannot be fully explained ...
