I looked at some of the rainfall graphs available from the European Climate Assessment & Dataset a month or two ago, and have now got the up to date data for 2019 and 2020. Also I have managed to fill in the gaps in the EAC&D dataset.

I have now replicated the above graph, which shows the highest day’s rainfall for each year:

The results appear to be pretty clear cut.The incidence of extreme rainfall at both Oxford and Durham has declined in recent decades, whilst at Buxton the reverse is true.

Nevertheless at the latter, the wettest day was back in 1973.

I do not claim any climatological significance in any of this. But what it does show though is that there is no evidence that a warmer atmosphere is driving more extreme rainfall.
