The picture is pretty much the same between 300M — 2000M, except a pooling of heat poleward of 40N below 1200M. (gfdl.noaa.gov)
As the ocean circulation takes up the role of transporting heat poleward the atmospheric circulation spins down. (realclimate.org)
I would suggest these small aerosols have a large effect on the saturated adiabatic cooling and heating cycles and the transport of water vapor latent heat poleward. (realclimate.org)
