Dear authors,

thanks for the effort you put into revising your manuscript. Your paper can be accepted for publication after considering the technical corrections given in the referee report and the ones given by me as follows:

- p1, l4 and 6: Additional the corresponding pressure level should be given in brackets.
- p4, l4: same here.
- p6, l8: "it should be kept in mind that WACCM is not fully realistic" The first two sentences of this paragraph sentence should be rephrased. "WACCM is not fully realistic" may easily be misunderstood. These two sentences could be combined in one stating that "a realistic representation/parameterisation of gravity waves in climate models is quite challenging". The recently published paper by Garcia et al. (2017), Journal of the Atmospheric Sciences could be helpful for discussing this problem in climate models.
- p6, l31: add the corresponding altitude in brackets.
- p14, Fig 4 caption: same here.

Best regards, Farahnaz Khosrawi
