What is the dry adiabatic lapse rate on Venus?
The dry adiabatic lapse rate (La)* on Venus is about 10.47K/km,
and is similar to that of Earth. This is because the La is governed
specific heat (Cp) of the atmospheric gasses and the
planet's gravity (g). Specific heat (Cp) is the amount of heat
energy in Joules required to raise the temperature of 1 kg of
substance by 1 Kelvin. The equation is quite simple. La = g/Cp For
Earth: Cp = 1.004 J/kg/K, g = 9.8 m/s2 Earth La = 9.76 K/km For
Venus: Cp = 0.85 J/kg/K, g = 8.9 m/s2 Venus La = 10.47 K/km For
Mars: Cp = 0.83 J/kg/K, g = 3.7 m/s2 Mars La = 4.50 K/km
The symbol for lapse rate is actually an upside-down L, but I don't
know how to do scientific symbols on this browser.
