possible roles in the increase of such extreme precipitation events over the region. Since the drivers and contributing atmospheric factors for summer and winter monsoons over WH are completely different, an effort has been made to explain the possible causes for increasing extremes for individual seasons separately. Based on the key findings from our study, the following conclusions can be drawn.


In summary, we would like to acknowledge that the substantial variations and the spatial heterogeneity in magnitude exist between different data products over WH mainly due to lack of in-situ data and complex orography. Such uncertainties can be reduced by increasing the coverage of ground-based in-situ observational networks over the region. The climate warming signal with its positive feedback mechanism in terms of enhancing the available moisture content in the atmosphere is a crucial factor influencing the rise of precipitation extremes over WH. Significant variations of various dynamics supported by local thermodynamic processes have also been observed, helping the growth and intensification of EPEs. However, future work is required to understand the underlying physical processes and their interactions with regional orography during such events to have a more elaborate understanding of the feeding mechanisms.
