Small-scale turbulence
and eddies transport
energy and heat.
These
become more realistic
with
higher resolution:
¥ eddy heat
transport:
¥ eddy kinetic
energy:
¥ feedback of
small-scale features on the large-scale mean flow - important for oceanic jets
¥ vertical
temperature profile
Reynolds decomposition:
total
time average
perturbation
note: SST and thus
heat flux is main influence on atmosphere for climate
cost of
