CHANDLER WOBBLE AND LOD ANOMALYES IN 2010-2020S
Preview AbstractIn early 2000-s the amplitude of the Chandler wobble (CW) started to decrease and in 2017-2020 reached its historic minima, comparable only with the minima of ∼1928 yr. In 2021 the CW appeared again. We demonstrate that the phase of the CW is changing now, as during 1920-1930s. Since 2010 it has changed almost by 2 radians, and we expect it will finally reach π radians. This implies splitting of the CW spectra into two pikes. Since 2016 the length of day LOD is decreasing and Earth’s rotation velocity is growing. In 2022 it is the highest over the last 90 years. We hypothesize that the anomalies of the CW are interrelated with LOD decrease through some synchronization and/or energy transfer?
