Аннотация:The observational data for 1979–2018 in the North Atlantic region have been used for the analysis of the heat fluxes. The spatiotemporal variability of the total heat flux that is sum of latent and sensible heat fluxes has been modeled by the stochastic diffusion process. The coefficients of the stochastic differential equation represented the stochastic process have been statistically defined from the original dataset. Earlier the existence and uniqueness of the solution in strong sense of stochastic differential equation generated by the constructed diffusion process have been proved such as the Kolmogorov conditions hold. In the current work the spatial and and long-term variability of the field of heat fluxes are analyzed. Based on the given series of 40 years in length from 1979 to 2018, some spatial maps and temporal curves were constructed. Numerical calculations realized on the Lomonosov-2 supercomputer of the Lomonosov Moscow State University.
