We propose a method of temperature fields for orthogonal decomposition of components. The territory of Russia and CIS countries was studied, as well as Northern Europe. Value of the long-term trend, the amplitude of the annual progress and the anomaly were calculated. Fields were built of multi-year minimum and maximum temperatures, the trend, the amplitude, and the seasonal component. The effect of the Gulf stream in the cold season was shown. Characteristics of temperature field for winter and summer periods were revealed.
