Description
Summary:Long-term trends are observed in the spatial variability of atmospheric circulation in the 18th–23rd solar cycles in the middle troposphere at the middle and high latitudes of the Northern Hemisphere. The intensification of solar activity in the cycle chronologically coincides with the formation of the extensive anomalies of geopotential at the level of 500 hPa over the northern parts of the Atlantic and Pacific oceans. Upper-level troughs gradually move from middle to high latitudes and, having reached the Arctic Ocean, start moving back to the south. The certain synchronization in the manifestation of natural processes on the Sun and Earth enables considering the features of the spatial distribution of natural anomalies for several solar cycles as a kind of the “marker” of natural long-term fluctuations.
