Brewer–Dobson Circulation: Recent-Past and Near-Future Trends Simulated by Chemistry-Climate Models

Figure 7

Trends in the eddy heat flux (units: K m s−1/decade) derived from the CCMs’ ensemble mean in DJF over the periods (a, b) 1960–2000 and (c, d) 2001–2050, in the SH ((a) and (c)) and NH ((b) and (d)). The contour intervals for the climatological eddy heat flux in the SH and NH are 0.5 K m s−1 and 2 K m s−1, respectively. Solid and dashed lines represent positive and negative contours, respectively. Stippled regions show the trends significant at the 95% level.
