14. Note that this choice means that, for an isotropic ensemble of one-turbule systems, the average temperature variation of the turbule is not zero, so its forward temperature scattering is not zero either. In order to obtain zero average temperature variation for the turbulence overall, as required by Eq. (6), we treat collections of turbules constrained so that the sum of their average temperature variations is zero.
