| Abstract | This study examines the effect of changes in aerosol concentration and solar radiation on thin, marine Stratocumulus with LWP of _50 g m-2 or less, i.e. non-precipitating marine Sc. The authors employ a liquid water budget analysis to demonstrate that aerosol effects on condensation in thin, non-precipitating marine Sc are more important than aerosol effects on precipitating processes in determining the overall cloud response. The overall results compare well with other studies on a similar subject, e.g Wang et. al, 2003; Bretherton et al, 2007; Hill et al, 2008, 2009. While the budget analysis demonstrates that condensation is more important than accretion or autoconversion, this paper fails to present the underlying mechanisms for the change in LWP with changes in aerosol. Previous work by a number of researchers (see below) has proposed mechanisms by which aerosol induced changes in condensation/evaporation influence cloud dynamics of non-precipitating clouds, which in turn leads to changes in LWP; however, none of this work is discussed or tested. Thus, while the results are comparable to previous work, such results have not been put into context, so it is hard to understand how original the conclusions are. Furthermore, I question the author’s rejection of the role of sedimentation in the LWP response to aerosol. This rejection seems to stem from overlooking some the aerosol-cloud-dynamic interactions discussed in previous work, interactions that would not be born out of their budget analysis. |
