Real EARTH (ERBE) net Radiation
Net heating at each latitude
What if HS was isothermal?
Net heating at each latitude - Isothermal
Held-Suarez Heat Transport
Realized=2.8 PW at 32o
Possible=6.2 PW at 26o
But, Dynamically the heat transport should be controlled by the temperature gradient

Farrell cell picks up heat transport to meet radiative constraintsIs this coincidental?
