6. Stratification according to the solar activity

6-1: QBO composites (W minus E) for the solar Min and Max years

Figures 5a - 5b

Composites with respect to the QBO phases by using only the Min years (upper) or the Max years (lower) for the zonal wind at 50hPa. Unlike the NH, the difference between the W and the E in the SH seems to be independent of the solar activity.

6-2: Solar composites (Max minus Min) for the QBO W and E years

Figures 6a - 6b

Composites with respect to the solar activity by using only the W years (upper) or the E years (lower) for the zonal wind at 50hPa. Unlike the NH, the difference between the Max and the Min in the SH seems to be independent of the QBO phases.
