Time series of advective and net chemical tendencies (unit: DU d⁻¹) for ozone tracers originating from the following regions across the Arctic: (a,b) ARCLS, (c,d) ARCMS, (e,f) NMLS, (g,h) NMMS, (i,j) TPLS, and (k,l) TPMS. All values are vertically integrated results from the tropopause to 20 hPa. The black, light blue, blue, orange, and pink lines represent the 7-year average, 2005, 2011, 2006, and 2009 results, respectively. The horizontal red line is the zero line. In Fig. 3c, the data from 05 January to 18 February are marked with a dark-green dashed box, which indicates when the mean advective tendencies during cold (warm) winters were above average (below average). Similarly, in Fig. 3e, data from 01 January to 28 February are marked with a dark-red dashed box, which indicates when the mean advective tendencies during cold (warm) winters were below average (above average). The black, light blue, blue, orange, and pink numbers in Fig. 3c,e represent the mean advective tendencies (unit: DU d⁻¹) during the periods within dashed boxes for the 7-year average, 2005, 2011, 2006, and 2009 results, respectively.
