What do you get with higher resolution?

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 doubling
horizontal grid
is factor of 10
