Dear Dr. De Luca,

Thank you very much for your positive evaluation of our manuscript and your constructive comments and suggestions.  Below please find our responses, presented in blue font following your comments in black font.

In addition, we have enclosed a draft of the revised manuscript, which largely incorporates the changes addressing your and other Reviewer’s comments, as detailed in the point-to-point responses. An assessment of the statistical significance of the composites shown in Figures 3 and 4 (in response to the corresponding comment) is not yet included, as this requires further data processing. The corresponding changes will be incorporated in the final revised version, together with the improvement of the colorbar of Figure 4 (in response to the respective minor comment).

Your sincerely,

Iana Strigunova, Frank Lunkeit, Nedjeljka Žagar, Damjan Jelić
