Soil Temperature Dynamics in Transbaikalia under Changing Climate Conditions

A. S. Balybina and I. E. Trofimova

The dynamics of multiyear mean thermal conditions in the 3.2-m soil layer in Transbaikalia is studied. A high correlation between variations in air temperature and soil temperature is revealed for summer, and low correlation is found for winter. The trends in cumulative soil temperature during the positive and negative temperature seasons are identified. The sum of negative soil temperatures at the depth of 80 cm exhibits an increasing multiyear trend. In cold seasons, the linear trends in soil temperature are stronger as compared to air temperature trends.
