Fig. 6

The left y-axes in this figure show the temporal evolution of \(R_{e}\) (black solid lines) during (a) 2006, (b) 2009, (c) 2010 and (d) 2013 NH SSWs while the right y-axes show the mean DW1 tidal amplitudes from SABER (purple dashed-dotted lines) and SD-WACCM-X (brown dashed lines) that are averaged between 30 S and 30 N at 90 km altitude. For comparison, the mean DW1 tidal amplitudes from SD-WACCM-X are scaled up by a factor of 2. The blue dotted lines show the climatological values of \(R_{e}\) (clim_\(R_{e}\)) and the red dotted lines mark the standard deviation associated with clim_\(R_{e}\) at ±2\(\sigma \) levels
