Poleward Flux of Energy
q Mosit Ststic Energy
      = sensible + latent + potential energy
      = Cp*T + L*q + g*z
q In a stably stratified atmosphere,
moist static energy increases with
altitude.
q A mean meridional circulation will
transport energy in the direction of
flow in the upper branch of the cell.
q The meridonal flux in mid-latitudes is
dominated by the transient eddy
fluxes, which is associated with the
weather systems.
