First six modes of variability from the DINEOF interpolated UVI dataset for the three windows at 283 nm. The first row is lined up in order of the PCs, while the second and third are rearranged so that similar patterns line up in the same column. The first mode shows a pattern similar to a Hadley circulation, while the second show a hemispheric oscillation. The third, fourth, and fifth columns appear to show a combination of short period atmospheric waves, while the sixth shows the well known Y-feature.
