Suggestions for revision or reasons for rejection

Most of my main concerns in the previous review have been answered to an acceptable degree.
As I said in my previous review, the analysis of CPs remains a little bit confusing. I do not understand why methods for the identification of multiple change points are important in the analysis presented in this paper and, thus, I would suggest removing the discussion about them in the final version of the text (any mention to results using BinSeg and PELT).
Some of the corrections and new paragraphs included in the new version of the text are confusing:
The new title makes no sense. Do authors want to emphasize the existence of a pattern in the ‘changes in the moisture transport…’, or the existence of changes in ‘the pattern of moisture transport for precipitation ASSOCIATED with Arctic sea ice melting’? I guess it is the second one. Could the new title be something like: ‘Changes in the long-term pattern of moisture transport for precipitation associated with Arctic sea ice melting’
Abstract, same question as before: ‘We have identified the patterns of change in…’ or ‘We have identified changes in the patterns of…’?
The new version of the first paragraph in section 2.2.2 is very confusing: review
The paragraph beginning in page 9, line 4 is confusing and should be reviewed…
Conclusions (page 12 line 4): Same question as in the title: 'The pattern of change' or 'a change of the pattern'? I find it is the pattern of MTP what changes. It is difficult to talk about a pattern of change from a single change point and thus, a single change case.

Some suggestions:
P5L1: the three different change point DETECTION methods
P6L2: ...the defined as the major moisture sources... -> ...those defined as major moisture sources...
P6L8: ...including the particles coming from the own Arctic region -> ...including the particles coming from the Arctic region itself
P6L10: ...2005), THIS works ... -> ...2005), it works...
P6L13: ...big enough -> ...high enough
P8L32: (red crosses) -> (red asterisks)
P12L3: ...which then results in precipitation over the Arctic (MTP) -> ...which then results in changes in the precipitation over the Arctic

Short summary

We have identified changes in the pattern of moisture transport for precipitation over the Arctic region, the Arctic Ocean, and its 13 main subdomains concurrent with the major sea ice decline that occurred in 2003. The pattern consists of a general decrease in moisture transport in summer and enhanced moisture transport in autumn and early winter, with different contributions depending on the moisture source and ocean subregion.
