AbstractDynamical theories of the Earth’s rotation like SMART97 (Bretagnon et al., 1998) are to be considered in a DGRS (dynamically nonrotating geocentric reference system) (Brumberg et al., 1996). Such a theory gives the explicit expressions in terms of TCG (Geocentric Coordinate Time) of three Euler angles relating a DGRS to the ITRS (International Terrestrial Reference System). These angular quantities together with their TCG derivatives enable one to get all Earth’s rotation parameters. At the same time, the analysis of observations result in the values for slightly different angles and their TCG derivatives characterizing the relationship between the ITRS and a KGRS (kinematically nonrotating geocentric reference system). The differences between these two sets of six quantities represent kinematical relativistic corrections (due to geodesic precession, geodesic nutation and luni-planetary terms). The paper presents these differences computed by means of the VSOP87 series (Bretagnon and Francou, 1988). In particular, in analysing observations at the microarcsecond level these expressions will permit an experimental check of geodesic precession in a more direct manner than it is done nowadays (Bertotti et al., 1987).

The Relationship

The article provides information about the relationship between changes in the global temperature on the Earth and variations in the speed of its rotation. Special attention is paid to the study of the correlation between the onset of abnormal warm and cold winters of the Eurasian continent and sharp changes in the Earth's rotation speed. It been observed, that during periods of rapid deceleration in the 20th and 21st century, there were abnormally cold winters, and during periods of acceleration, abnormally warm ones. Thus, the periods of acceleration and deceleration of the Earth's rotation speed fell respectively on warm or cold winters in all cases, except for the winter of 1964/65 g., when the Earth's rotation occurred relatively evenly. Based on the obtained 90 % correlation of the number of coincidences of anamal winters with sharp changes in the speed of EW, as well as the calculated forecast of the Earth's rotation speed up to 2030, it is concluded that from 2024 to 2026 g, anamol cold winter should be expected in Russia and Europe

The Relationship

Analysis of observations of the Earth's rotational velocity and volcanic activity of the planet from 1720 until 2015 suggests that higher volcanic activity temporally coincided with periods of decreased angular velocity of Earth's rotation (deceleration), and, vice versa, lower volcanic activity coincided with the periods of increased velocity of the Earth's rotation (acceleration). Our analysis employed the data from the catalog by the Smithsonian Institute, United States, in which each volcanic explosion had its own determined value of the Volcanic Explosivity Index (VEI). The total number of selected intensive eruptions with VEI > 4 was 160, including 25 eruptions with VEI > 5. At present (beginning from 2006), the Earth was entry in a deceleration phase and series of catastrophic eruptions reveals the tendency toward intensifying volcanic activity.
