| Summary: | Abstract Under the influence of large planets (Jupiter, Saturn, Uranus, Neptune), the Sun moves in outer space along a certain trajectory around the common center of mass of the solar system. Earth follows the sun. It is assumed that part of the barycentric rotation moment is transmitted to the Earth’s rotational moment and zonal currents of the World Ocean. The aim of this work is to obtain estimates of the possible impact on the climate system of additional rotation forces arising on the Earth during the barycentric movement of the Sun around the common center of mass of the Solar system. The climate system is considered as an oscillatory system, which can resonantly perceive external repetitive effects at its own frequencies. The index of the dynamic influence of barycentric rotation on the speed of the axial rotation of the Earth, on the surface temperature of the ocean and on El Nino is proposed. An asynchronous correlation analysis is performed. It is shown that the influence of the dynamic forces of barycentric rotation describe 31% of the total variability of the Earth’s rotation speed with a delay of 5 years, 66% describes the variability of the average annual temperature of the ocean surface in the circumpolar Antarctic current with a delay of 32-37 years. The contribution of the moment of inertia to the total SST variability along other ocean currents is from 25 to 50% with the same delay. It was found that the El Nino phenomenon is a consequence of variations in the circular circulation of oceanic waters in each of the hemispheres of the Pacific Ocean. One of the engines of these variations are perturbations of the ocean circulation in the region of the Antarctic current. The contribution of changes in SST in the Antarctic Current to changes in the NINO3 index is 31%. |
