Hi Haitham,

it is really difficult to help you like this. You have many post on this forum about rainfall events. Try to write a script, and then, we can help you. For instance, you want to calculate the extreme rainfall events. Upon looking on internet, it seems that it is defined by "the 95th percentile of the cumulative frequency distribution of daily precipitation". The documentation explains this really well with several examples (see 2.8.22 in Documentation).

Regards,

Estanislao

the climate indices package ECA (https://code.mpimet.mpg.de/projects/cdo/embedded/cdo_eca.pdf) has methods for that, too
