Dear Author:

I find a substantial improvement in the revised MS
and the authors have the referee concerns. Thank you for revising the MS.
The MS is now ready for publication in ACP, but
please consider the below-given suggestions too.

Many thanks and Kind regards
J. Kuttippurath

L60-73: One important reference missing in this section is Varikoden et al. doi.org/10.1007/s00382-018-4397-7. They discuss how the rainfall changed over WG in the past decades, and the differences in rainfall trends in the northern and southern WG.
L67: “region, and found that the larger drops are relatively higher at Munnar”
L71-72: can you write the mid and high altitudes in km here?
L80: Can you write the answers to these five points in Abstract?
L112: “small drops do not significantly affect”

Conclusions: There are eight points and some are discussed in the text and are not new. Please give the new information from your study here.

Figure 8, 9, and 10: Make the y-axis uniform with respect to the values (give a common range) so that we can compare them. Also, combine all three to single figure with sub-plots.

Figure 16: is should be introduced in the last paragraph of the discussion, not in conclusion.

Short summary

Indian summer monsoon (ISM) rainfall exhibits sub-seasonal variability as active spells with good rainfall (wet spell) and weak spells or breaks with little to no rainfall (dry spell). Studies have shown that during the wet and dry periods of the ISM, there are contrasting behaviors in the formation of weather systems and large-scale instability. Thus, it is worth investigating how the raindrop size distribution varies during intra-seasonal timescale variations of the ISM in the Western Ghats.
