The climate system of the Earth is among the most complex natural systems. It is very dynamic, nonlinear, highly sensitive and difficult to predict, with chaotic processes that embrace the atmosphere, oceans, continents, biosphere and cryosphere. Besides, it depends on the large-scale atmospheric circulation dynamics, the dynamics of the oceanic and sea basins and the frequency and strength of the extreme meteorological phenomena. The climate system was formed under the continuous influence of external (astronomical and orbital) and internal (earthly - geophysical, geological and geographical) factors.
The immense role of the hot spots for the thermal dynamics of the oceans must be recognized. Apparently the heat flow of hot spots exerts a certain influence on some meteorological phenomena and climatic variations. Besides the spatial behaviour of ENSO (El Nino and La Nina), NAO (Azores and Iceland), as well as some other factors, smaller oscillations suggest the idea of substantial connection and impact of the Earth's inner dynamic and the hot spots on certain meteorological phenomena with effect on the climatic changes. In the light of recent data on the Earth's internal dynamics, the plate tectonics, mantle hot spots spatial distribution, the dynamics of the atmospheric phenomena and the climatic change cycles a contemporary theory on the relation of Earth's dynamics and climatic changes could be developed.
