Correlation analysis of the interaction between oceanic heat fluxes and the geopotential gradient fields in the middle troposphere during meridional and zonal processes

Abstract

Investigation of the interaction between oceanic heat fluxes and formation of the geopotential gradient fields in the middle troposphere during meridional and zonal processes has been carried out by applying linear correlation analysis. Analysis of the spatial distribution of the correlation coefficients has demonstrated that the structure of the interaction of heat fluxes in the North Atlantic with the geopotential gradient field in the middle troposphere over the Atlantic-European sector differs in periods with the predominance of meridional and zonal circulation forms, which indicates the significant role of the ocean heat flow in the formation and development of circulation regimes in the atmosphere.
