Long-range forecasting of the dates of the stable 8°C crossing in average daily air temperature in the Volga Federal District

Аннотация

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 8°C 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 8°C in the district.
