Suggestions for revision or reasons for rejection

The authors has essentially revised the manuscript according to my questions and comments. However, one minor but important aspect needs to be addressed. The Dalton and Stanton numbers presented In eq. 1-2 are unfortunately not the ones I was referring to. I am referring to the numbers used in bulk parameterizations of air-sea fluxes see e.g.

Drennan, W. M. (2006), On parameterisations of air‐sea fluxes, in Atmosphere‐Ocean Interactions, vol. 2, edited by W. Perrie, pp. 1–34, WIT Press, Southampton, U. K.

A well known algorithm is the COARE algorithm, see e.g.

Fairall, C.W., E.F. Bradley, J.E. Hare, A.A. Grachev, and J.B. Edson, 2003: Bulk Parameterization of Air–Sea Fluxes: Updates and Verification for the COARE Algorithm. J. Climate, 16, 571–591

It is more relevant to compare with these versions of the exchange coefficients and e.g. plot them as function of wind speed, compare values during the different periods (pre-, during and post- monsoon), also put them in context, e.g. compare with values from COARE algorithm. In this way you can directly see if your measurements go beyond current state-of-the art knowledge of air-water energy transport (which the COARE algorithm aiming to represent).

The current discussion on Fig 8 and the current versions of the Stanton and Dalton numbers unfortunately doesn’t add more understanding of the results. If you argue to keep it, my view is that you need to elaborate more on the interpretation of these results.

Figure 9, figure caption, Please double check the caption. Clearly state what upper and lower limits of the large box represent. What does the horizontal line in each box represent? Also how can the 1 and 99% percentiles go beyond the maximum and minimum values represented by the short dash (as I interpret as the whiskers)?

Short summary

Erhai Lake is a subtropical highland shallow lake on the southeast margin of the Tibetan Plateau, which is influenced by both South Asian and East Asian summer monsoons. The substantial difference in atmospheric properties during monsoon and non-monsoon periods has a large effect in regulating turbulent heat and carbon dioxide exchange processes over Erhai Lake. Large difference are found for the factors controlling sensible heat and carbon dioxide flux during monsoon and non-monsoon periods.
