Aerosol-Induced Invigoration of Cumulus Clouds—A Review

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This paper presents a personal review of the invigoration of cumulus
clouds by high concentrations of ice nucleating particles and    
hygroscopic aerosols. It is based on a keynote talk presented by the
author, as stated in abstract and as such describes research on the
topic over the period of the author's career, including the extensive
model simulations of clouds and cloud systems performed by the author
and his group. It is an interesting and important review that provides a
fresh perspective at a time when further research is required to
understand the influence of aerosols on updraft speed. It includes
personal anecdotes which are both interesting and informative.


Minor comments that the author may wish to consider.

Lines 166-178. Is there a reference for this work?  

Lines 185-195. Perhaps mention the calculations of Cooper, Bruintjes and
Mather (1997) concerning the possible effects of hygroscopic seeding
with flares for the South African seeding experiments.

The Mather et al reference should be 1997.

Should it be pointed out that the "dynamic signature of seeding"
mentioned by Bigg (1997) is slightly different to the enhanced latent
heat argument?

Lines 196-198. This final implication is somewhat surprising given that
larger cloud drops compete much more effectively for the available water
vapor than small ones. Might this be particularly important if entrainment
is taken into account?

Section 3.4. Should entrainment be mentioned in this section? It
has been highlighted by others as an important process to include in
consideration of aerosol-induced invigoration of cumulus clouds.

Reviewer 2 Report

Comments and Suggestions for Authors

The manuscript titled "Aerosol-Induced Invigoration of Cumulus Clouds—A Review" is a short communication based on Professor William R. Cotton's presentation at ICCP 2021, focusing on the invigoration of cumulus clouds. It provides interesting and informative insights that can benefit students and early-career scientists. I recommend accepting this manuscript in its current form, with the exception of a minor typo: the heading for section 3.1 is missing.

Author Response

Thank you for your supportive review of the manuscript. I added a heading to Section 3.1

Reviewer 3 Report

Comments and Suggestions for Authors

In the present manuscript, the author has presented an extensive review on Aerosol-Induced Invigoration of Cumulus Clouds with his vast academic and research experience in the field of cloud micro physics and meso scale meteorology. Though the manuscript is very informative for the scientific community, I suggest some minor corrections can be done before being accepted for the publication. Minor suggestions are as follows

The abstract, introduction and first para of section 2 are more like self introduction rather than information about the presented manuscript. I suggest the authors to revise.

Few figures may be included which will be very much useful for the young researchers who are newly working in this filed and makes this review paper a great reference.

 

 

 

 

 

Author Response

Thank you for your supportive review of the manuscript.

I revised the abstract to be more informative to the readers, rather than being a self-introduction.

 

I agree some figures might be useful, something like the figures in Danny Rosenfeld’s articles. But I have little artistic talent and no longer have a support staff to help me(I am fully retired).
