Reviewer 1 Report
In my opinion, this manuscript should be classified as a technical note, and not as an article, because it seems an application of well-known procedures for a specific case study, and it does not regard a development of a new model

Reviewer 3 Report
The relationship between interdecadal variability of summer monsoon rainfall change and the PDO and AMO indices is shown, employing a rich and rigorous statistical analysis including, among others, trend/EOF/SVD analyses and composite/correlation methods. The language suffers from numerous expression errors, such as incorrect use of the tenses for verbs (my corrections below for lines 106 to 120 is small illustration). A serious revision of English is required.
Some minor tecnical corrections/comments (line numbers in parenthesis):
44: According to the main conclusions, AMO and PDO have a greater chance to be highlighted as keywords than ENSO?
85: You may want to add a sentence on the human-driven future projected precipitation changes in the region (Almazroui et al., 2020; Tangang et al., 2020; Ge et al., 2021).
106: Rephrase to "Here, the method of Empirical Orthogonal Function (EOF) is used to analyze the decadal..."
110: Better use the verb in the present tense here: "This study aims to fill the gap..."
114: Correct to "... considers the (May to October) months...".
116: Correct to: "Section 2 describes data...".
119-120: It would really help the reader position Myanmanr in SE Asia if you add a second map inside Fig. 1 where this region is shown, indicating with a rectangle the country of interest within the region.
line 172: "... (Engine vectors)..." here you must mean Eigen vectors.
211-212: Almazroui and Sen (2020) present a very relevant review of both trend methods.
213-219: Are all these symbols and equations needed to support the subsequent work?
278: In Fig.2 you may consider adding errors bars (of 2 x std) to depict the variation due to inter-annual variability?
415: Correct to "... Markov Analysis".

Reviewer 4 Report
The present study investigates the interdecadal variability of monsoon rainfall in the Myanmar region. The gauge-based gridded rainfall dataset of Global Precipitation Climatology Centre 20 and Climatic Research Unit version TS4.0 are used to investigate the interdecadal variability of summer monsoon rainfall by using Empirical Orthogonal Function, , Singular Value Decomposition and correlation approaches. This paper’s results are interesting and thus suitable for publication in Water, MDPI. There are only small comments as follows.
- Line 201: q is the specific humidity = Vh => q is the specific humidity, Vh
- Table 1: Write the unit of rainfall.
- Table 2: Write the unit of RMSE value.
- Figure 2: The continuous lines in this diagram cause misunderstanding that the quantities are continuous. In reality, however, it is monthly data. Draw it more properly.
- Table 3: There is no necessity to show the rainfall in terms inches.
- Line 461: Fig. S1?
- Line 385 -- : Write down equations used for EOF analysis in more details, as there are several modified versions in this analysis method.
