Long-range Forecasting of the Dates of the Stable 8C Crossing in Average Daily Air Temperature in the Volga Federal District

N. A. Vazhnova and M. A. Vereshchagin

Physical principles are considered of asynchronous long-period relationships between the thermal state of the North Atlantic and the dates of the stable average daily air temperature crossing 8C in spring and autumn in the Volga Federal District. The methodology and the results are discussed of testing the informativeness of the fields of sea surface temperature anomalies for long-range forecasting of the dates of the stable average daily air temperature crossing 8C in the district.
