An amazing period of weather, an unusually cold November, an unusually wet December, an unusually mild January, an unusually wet February and an unusually cold and "wet" March.

4 of them in the top 10 of either CET or the 1772 rainfall series.

That was a bizarre run of weather from Nov 1915 to March 1916. I'm hoping to do a historic video on that period sometime.


The whole period from 1915 to 1919 was fun in terms of the weather though, with lot's of odd and extreme months.


1920's were compratively dull (until towards the end of the decade anyway)

Here are the 500hpa anomalies of the months discussed

November 1915: good blocking in North Atlantic

UserPostedImage

December 1915: very cyclonic, no wonder it was so wet

UserPostedImage


January 1916: Bartlett type set up hence why it was so mild

UserPostedImage

February 1916: very cyclonic

UserPostedImage

March 1916: Greenland blocking with greater cyclonicity, hence why it was wet with frequent snowfalls
