Temporal correlation coefficient between the MA mean index of northern Indochina biomass burning activities (i.e., the amount of MODIS fire count over the domain of 17–22°N, 97–102°E; red boxed area) and six selected variables: (a) GFDE4s total biomass burning dry matter emissions, (b) 850 hPa wind circulation V (850 hPa), (c) 700 hPa wind circulation V (700 hPa), (d) stream function of the moisture flux ψQ, (e) potential function of the moisture flux χQ, and (f) precipitation P extracted from TRMM observations. The time period of correlation is from 2005 to 2015. Only the areas with significant changes (at the 90% confidence interval) are shaded/shown. The color scale of Figures 4a–4f is given in the bottom plot.
