| Summary: | A General System theory of the influence of the Earth’s nutation on the temperature of the Barents Sea is presented. According to this theory, the Earth’s axis behaves dynamically as a forced oscillator on a non-linear sea system that modulates a set of harmonic and subharmonic low-frequency temperature cycles. A spectrum analysis of the Kola meridian sea temperature time series indicates a correlation between it and the Earth nutation cycles of 18.6yr, 18.6/3=6.2yr, and 18.6×3=55.8yr. The 55.8yr cycle seems to follow a moving average in the temperature series. If the theory is confirmed by the analysis of other data sets it will open new perspectives in the forecasting of future temperature, ecological, and biological changes not only in the Barents Sea but also worldwide. |
