The work discusses the mechanisms operating within the climate system leading to variability and changes in the atmospheric climate over Europe. The second part presents the impact of SLP changes over the Barents Sea modifying the effect of NA THC on the course of circulation processes in the Atlantic-Eurasian circulation sector. SLP changes over the Barents Sea, which are the result of the time-delayed action of NA THC, significantly influence the variability of climatic elements over Poland and Europe. The combined synchronous effect of NA THC changes and SLP changes over the Barents Sea as determined by the North Atlantic Climate Index (WKNA) explains 76% of the variance in annual mean temperature over Europe over the period 1951–2020. The additional inclusion of radiative forcing (ΔF), which is generally considered to be the main factor forcing temperature increases, increases the explanation of temperature changes to only 80%. This allows us to put forward the thesis that the impact of changes in CO2 concentration on the increase in air temperature over Europe plays a negligible role in relation to the action of natural factors. The main role in shaping climate change over the last 70 years has been played by changes in the intensity of meridional ocean heat transport in the N Atlantic. |
