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

Figure 2

Period ranges (PR, -labels) and their occurring-probability (OP, %). , set as the abscissa/ordinate, is the zonal/meridional speed component for magma within the lower mantle/outer core (μm/s, above/below the frame in Rows a, b, c, and d). Columns 1–3/4–6 provide the periodicity of zonal/meridional motion at the labeled latitudes (north is positive). OP is the ratio of the shaded area for PR to the total area labeled on the “” column, computed using (6). The OP averaged for Columns 1–6 is labeled on the “OP” column.
