Dear Authors,
I would like to suggest a major revision of this work based on the comments raised by the reviewers and on my own judgement. Please pay special attentions to:
1) Highlight the significance of the work;
2) recalculate based on the generalised CR model (Brutsaert, 2015, Han et al., 2012), as suggested by the Referee #3;
3) P.2, line 1, “and soil water storage (Li et al., 2013; Yang et al., 2007).” ---> 'and soil water storage (Li et al., 2013; Yang et al., 2007), catchment slope (Yang et al., 2014)”
Yang, H., Qi, J., Xu, X., Yang, D., and Lv, H.: The regional variation in climate elasticity and climate contribution to runoff across China, Journal of Hydrology, 517, 607–616, 2014

Thanks for the contribution and for your patience.

Best,

Dear Authors,
I would like to suggest a minor revision of this work based on the comments raised by the reviewers and on my own judgement. Please pay special attentions to:
1) Re-clarify the statement on the timescale of the Budyko and complementary relationship, as suggested by the Referee #3. Although the Budyko curve has been applied fo the season or month, the equation used in the manuscript (with precipitation as water availability) is valid only at a longtime scale.
2) Revise the typos
Thanks for the contribution.
