According to the NCEP/NCAR Reanalysis data, synchronous long-term changes in the surface thermobaric field occur over the vast territory of Asia, including Southern Siberia, in the equatorial and tropical Indian and Pacific, in Africa, and in the circumantarctic depression. The relation between these changes can be caused by changes in the El Nino occurrence or by transequatorial mass transfer. The correlation coefficients of surface pressure variations with variations of the ocean surface temperature in the El Nino zone and pressure variations in the circumantarctic depression are estimated. The results indicate that the most probable relating processes are the processes on inter-hemispheric interaction.
