Presentation Transcript

  1. Energetics Basic forms of energy Observed energy balance (transport)

  2. 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

  3. Energy in theAtmosphereInternal,Potential,Latent(70.4,27.1,2.5)%

  4. 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

  5. Mechanisms of Releasing Energy (Baroclinic Instability) (a)-unstable case
