The moisture transport from its sources to the continents is one of the most relevant topics in the hydrology, and its role in extremes events is crucial to understand several processes in the Earth, as intense precipitations and/or flooding. Using the global precipitation (P) dataset from the Multi-Source Weighted-Ensemble Precipitation (MSWEP) from 1980 to 2015 with a 3-hourly temporal and 0.25° spatial resolution, a monthly precipitation climatology were done over the area of the Mediterranean Sea, checking grid by grid which year exhibits the maximum precipitation. As is well known, the Mediterranean Basin is a clear source of moisture for the surrounding areas. To link this source of moisture with the precipitation, in this work we have made use of the Lagrangian dispersion model FLEXPART to track, in its forward mode, those particles that monthly leave the Mediterranean Basin and we have calculated the loss of moisture (E-P<0) modelled by FLEXPART (P-FLEX) over the continental region. The aim of this study is to calculate the monthly climatological percentage of the Mediterranean contribution grid by grid, and the changes of this contribution for extreme monthly precipitation checking the importance of this sea source of moisture during the maximum peak of precipitation.

August and October results
Dear authors,

It is a very interesting paper. From the text I extract that, despite only September is analyzed, the calculations were realized for August and October too. Did you found important diferences in the results for these months?

Kind regards,

Dear Marta,

Thank you so much for the comment.
The results showed the similar pattern for both months (August and September) because for the Mediterranean region this period (August-October) is estimated as well most precipitative period during the year. We chose to present September in the paper, bacuse many investigation say that this is month with recorded maximum precipitation in Mediterranean region.

Kind regards,
