Round 1

Reviewer 1 Report

I went through the manuscript thoroughly and realized that the others followed the same pathway of scale decomposition already used by one of the authors previously in a number of papers. The current paper shows the numerical justification of the significance of baropycnal work in energy transfer across scales. The baropycnal work is modelled as a nonlinear model in the current work.

The work is interesting and can be recommended for publication after some clarifications. I first request the authors to discuss in section 2.1 the physical reason of the decomposition of the kinetic energy as \sqrt \rho u * \sqrt \rho u instead of \rho u *u where the second decomposition looks more physical and can be easily seen in the Navier Stokes equation. I think this is important.

Then I also request the authors to explain more clearly the derivation of \Lambda_M. For example, they assumed the scale locality in compressible turbulence following Eyink (Physica D, 2005) paper which was done for incompressible turbulence.

and a very minor thing. Correct the spelling of 'characteristics' in the very first line.

I will decide the recommendation after their review.
