Abstract
<jats:p>The article examines the nature of changes in the pressure field at the Earth’s surface around the globe during two natural climatic periods ofthe Earth’sclimatesystem–thestabilization period andthesecondwave of globalwarming in July.The pressure fieldwas approximated by the geopotential field of the surface H0. In the northern hemisphere, no differences in the structure of the geopotential field of the H0 surface were found in the two natural climatic periods. In the southern hemisphere, there are noticeable differences related to the localization of foci of high and low values of the geopotential height of the surface H0. Therefore, it can be concluded that the identified foci emphasize the peculiarity of global warming – its seasonality, namely, the increase in temperatures in thecold part of the year. Itis noted that the identified foci of elevated and lowered geopotential heights may indicate the presence of some kind of oscillatory structure in the southern hemisphere.</jats:p>
