Energetics

Basic forms of energy

Observed energy balance (transport)


Basic forms of energy

For a unit area column:

I=cvT –Internal Energy

=gz –Gravitational-potential

LH=Lq –Latent Energy

K=1/2(u2+v2) –Kinetic Energy

E=I++LH+K

-Total Potential Energy (Enthalpy)

Rd/cv2/5


Energy in the atmosphere internal potential latent 70 4 27 1 2 5

Meridional transport of energy
Meridional transport of energy

The meridional eddy transport

of potential energy 0

In adiabatic atmosphere

gdz=-cpdT,

That is a compensation of the heat flux with those of potential energy
