Abstract
In this paper to investigate the structure and dynamics of temperature fields of the different spatial and temporal scale, the structure selection methods was applied. For the study, the monthly mean air temperature of 249 stations in northern Eurasia during the period 1955-2010 were involved. The fields of the average monthly temperature for each calendar month were classified. The average temperature in the annual behaviour have been built. The study revealed that structures with large areas are allocated, within which formed pockets of air masses of different origin are formed. Centers of origin of air masses, uniform temperature field and contrasting transitional zone between them are refined.
