But London is drier than those places even when you look at number of rainy days or hours of rainfall.

London may have less days of sun but you cannot compare London a place where rain = overcast or dirzzle most of the time to a German city that gets quick thunderstorms in summer.

I know London has less sun. It also has less time with rain falling... aka you are more likely to get rained on in Paris or Karlsruhe than you are in London. Those summer thunderstorms last longer than summer showers in London do. Why is that so difficult to understand?

Thank you for the link!

I have searched for the original source and have found the Observatories' year book 1927 (Kew Observatory precipitation hours are from 1927-1956).

http://www.geomag.bgs.ac.uk/data_ser...SKLER_1927.pdf

(a pretty large file, Kew Observatory rainfall data is from page 370 onwards)

The precipitation hour data is more precise than what I calculated with German Weather Service data in another thread. ben86 gave me the idea to srutinize the recording method of precipitation hours: in the German data it counts as two hours of rain if it rains for two minutes from 3.59 pm to 4.01 pm. In that document above, p. 370 one can see for example on January 5 precipitation was recorded at five hourly intervalls, but the denoted duration is only 2.8 hours for that day.
Therefore German and British data about precipitation duration are not really comparable to say one place sees rain for a longer period of time than another.
