Polarward Energy
Transport
Annual-Mean Radiative Energy
Polarward Heat Flux
Polarward heat
flux is needed to transport radiative energy from the tropics to
higher latitudes
The atmosphere
dominates the polarward heat transport at middle and high
latitudes. The ocean dominates the transport at lower
latitudes.
