Abstract

In a recent paper, Wagner and Graf derived a population evolution equation for an ensemble of convective plumes, an analog with the Lotka–Volterra equation, from the energy equations for convective plumes provided by Arakawa and Schubert. Although their proposal is interesting, as the present note shows, there are some problems with their derivation.
