SAMI3/WACCM-X EOFs for 2–31 January 2014 (1200 UTC). (a) – (c) The spatial pattern of the EOFs 1, 2, and 3 with the color label at the bottom. Thin black lines are SZA on 16 January 2014 at 10°, 20°, …, 90°. (d) – (f) The amplitudes of each EOF (black lines) along with the indices F10.7 (red lines) and Ap (blue lines), linearly scaled to provide the best fit to each of the amplitudes. The correlation coefficients of amplitudes with respect to the indices provide for each EOF at the bottom, along with the significance p-value, where p < 0.050 is 95% confidence level.
