Тепловое поле южно-таежного ландшафта Русской равнины

The technology of allocation of order parameters (invariants) of the spatial structure of the thermal field of the southern taiga landscape (Central Forest Nature Reserve) obtained on the basis of the analysis of the time series of measurements in the long-wave channel of Landsat satellites from 1986 to 2017 and reflecting its stationary state is considered. It is shown that the heat flux is measured by the satellite not directly from the forest crowns, but from the ground layer of the atmosphere, the state of which is determined by the parameters of the landscape. It is found that the invariant component of the spatiotemporal variation of the thermal field is displayed by two order parameters: the first mainly reflects the temperature of winter months, the second — of summer. The contribution of relief and vegetation to the determination of invariants and the autochthonous components of the thermal field determined by the transition zones between the landscape elements contrasting in thermal radiation are revealed. It is shown that the thermal field measured by the satellite reflects the heat flux from the ground layer of the atmosphere, which is in direct interaction with the landscape cover.
