Temporal correlation coefficient between the MA mean index of northern Indochina biomass burning activities (defined in Figure 4) and two selected variables: (a) multilevel vertical motion (−ω; the positive values denote the upward motions) and (b) multilevel westerly wind (u) averaged over 17–22°N. (c and d) Similar to Figures 6a and 6b, respectively, but for the temporal correlation coefficient between the MA mean index of southern Indochina biomass burning activities (defined in Figure 5) and the selected −ω and u averaged over 10–15°N. The time period of correlation is from 2005 to 2015. The topography is marked. Only the areas with significant changes (at the 90% confidence interval) are shaded.
