Fig. 1

The top panels present the daily zonal-mean temperature (K) averaged between 70\(^\circ \)N and 80\(^\circ \)N as a function of pressure levels from SD-WACCM-X simulations for (a) 2006, (b) 2009, (c) 2010 and (d) 2013 NH SSWs. The bottom panels present the SD-WACCM-X simulated daily zonal-mean zonal winds (m/s) at 60\(^\circ \)N as a function of pressure levels for the above-mentioned SSWs in e–h. The black dashed lines mark the day of polar vortex weakening (PVW) for the corresponding SSWs
