REMARKS ON NATURAL-CONVECTION AS A HEAT ENGINE - REPLY

Emanuel and Bister discussed results of numerical experiments in which the radiative cooling rate of the atmosphere was arbitrarily specifie d. They suggested that the seating theory for atmospheric convection p roposed by Renno and Ingersoll is not consistent with these results an d proposed an alternative theory. Klein, in turn, argued that the resu lts of these numerical experiments are consistent with the scaling the ory proposed by Renno and Ingersoll. The author shows further evidence in support of Klein's arguments. Furthermore, it is shown that the al ternative scaling theory proposed by Emanuel and Bister, though intere sting, possesses a thermodynamic inconsistency.
