The linearized system may be reduced to a second-orderone satisfied by the respective fluid streamfunctions. For the two-species case, the electron mass is aparameter small enough for a WKB asymptotic analysis to be justified. It turns out that the pointswhere either the ion or electron equilibrium velocity equals the ratio between the temporaland transversal frequencies of the perturbation are turning or singular points of the system,connecting exponentially increasing or decreasing solutions to oscillatory ones. The crucial role ofsingular points in the balance between the different contributions to the electron kinetic energy isexplored.
