Interrelation of the phenological phenomena of the winter season at northern macroslope of Hamar-Daban ridge (South Pribaikalye) with the thermal properties of soil

Results of long-term researches of subseasons duration of winter period, and also dates of their beginning and ending on northern macroslope of Hamar-Daban ridge are presented. Correlation relation between some phenological phenomena of a winter season is characterized. Use the parameters of soil thermal condition as the additional phenological indicator for the description of natural complex is proved.
