Query on how to select an Extreme Event Analysis method

CLIMsystems: With extreme high precipitation (only variable combination you are getting this choice) we apply Daily GCM GEV value changes.

This method is based on GCM outputs to find the change in (modelled) extreme values. It is capable of producing higher extremes even while the annual precipitation is going down. We know that in many of these places it "rains less, but when it rains, it rains harder".

For some types of analysis sub-daily analysis is appropriate as exemplified by the graphic below for Washington D.C. In general but not applicable to all locations is that sub daily rainfall intensities are more intense than daily and this can have implications for certain infrastructural and building designs.
