Energetics

This text explores the fundamental forms of energy within a unit area column, including internal energy, gravitational potential energy, latent energy, and kinetic energy. It presents a comprehensive equation for total potential energy (enthalpy), emphasizing the internal distribution of energy in the atmosphere: 70.4% internal, 27.1% potential, and 2.5% latent. The analysis also highlights meridional energy transport, the role of adiabatic processes in heat flux compensation, and the mechanisms behind energy release through baroclinic instability in unstable cases, shedding light on atmospheric dynamics.

  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
