Abstract
Investigation of the interaction between oceanic heat fluxes and fields of the spatial gradient of the geopotential in the middle troposphere has been carried out by means of linear correlation analysis when meridional and zonal processes are active. Analysis of the spatial distribution of the correlation coefficients demonstrated that the structure of the interaction between heat fluxes in the North Atlantic and the geopotential gradient field in the middle troposphere over the Atlantic–European sector differs in periods with predominant meridional and zonal forms of circulation, which provides evidence on the significant contribution of ocean heat flux to the formation and development of atmospheric circulation regimes.

Funding
The study was performed within a state task (no. 0149-2018-0001). The fields of the absolute value of geopotential gradients for meridional and zonal processes were calculated with the support of a grant from the Government of Russian Federation for State Support of Scientific Studies under the Supervision of Leading Scientists (project no. 14.B25.31.0026). Calculation of correlations and analysis of the results were supported by the Russian Science Foundation (project no. 14-50-00095).
