Astronomy and Climate-Earth System: Can Magma Motion under Sun-Moon Gravitation Contribute to Paleoclimatic Variations and Earth’s Heat?

Figure 3

Squared-amplitude spectra for the total PSMGIM time series (TW²). The experimental dissipation coefficient for magma within the outer core was set at 10⁻⁴ (left column) and 10⁻³ s⁻¹ (right column) and enlarged by 100% (Row 1), 150% (Row 2), and 200% (Row 3) for magma within the lower mantle. The total PSMGIM time series (not plotted) was 100% and was correlated with its reconstruction via the Discrete Fourier Transform (DFT) with a confidence of 99.99% and was evaluated using the following: (1) the maximum size of the positive/negative amplitude of its anomaly (“”), (2) the total phase length during positive-/negative-anomaly phases (“”), (3) the standard deviation (“STD”), and (4) the mean (“”). Parameters , , and are described in Section 2.
