• "In El Nino the tropical atmosphere warms, and the vertical structure of this warming is indeed close to that obtained by assuming that the atmosphere stays near a moist adiabat, that is, the warming is substantially larger in the upper troposphere than near the surface."
• "Moist adiabats are much more complicated than the dry adiabat."
• "“At typical Earth-like surface temperatures, the effect is very strong: for a starting temperature of 5ºC, the mean lapse rate over the first 5 km is 7.2 K km−1, for 20ºC it is 4.8ºC km−1 and for 35ºC it is 3.3ºC km−1 compare with 9.8ºC km−1 for the dry adiabat."
