Results of calculations of heat fluxes (kinematic temperature fluxes) in the surface air layer are discussed based on experimental data on variations in the air temperature and wind vector components on different scales for a territory with a natural landscape (at two altitudes in the surface layer) and an urbanized territory. A conclusion is drawn about the necessity of taking into account local-scale heat fluxes along with fluxes of the turbulent scale when predicting the state of the atmosphere using high spatial resolution models.
