The average parameters of cold-season temperature are presented for all stations in the northern permafrost zone of Russia for different periods in 1930-2017. Ratio of the temperature parameters (sum of winter Temperature, winter Temperature mean, Temperature January) to δ¹⁸O values is given for all stations on average (the coefficient Y in the equation Ti=Y⋅δ¹⁸O).
