It's also substantially more than the lowest annual rainfall ever recorded anywhere in England, which if memory serves was 9 point something inches somewhere in Essex in 1921. -- John Hall "[It was] so steep that at intervals the street broke into steps, like a person breaking into giggles or hiccups, and then resumed its sober climb, until it had another fit of steps."

It was Margate (Cliftonville) in Kent which saw an annual total of just 236 mm (9.29 inches) in 1921, which remains the lowest accepted annual rainfall total on record anywhere in the British Isles. In the context of the Seathwaite discussion, the latter saw this amount fall in just under 16 hours on Thursday last. I am slightly surprsied that none of the media references that I've heard to the actual rainfall totals recorded at Seathwaite have placed this '370 mm' total in this context, nor of 'six months rainfall in London in 34 hours', for example: a pity because I suspect outside the audiience of this ng and a few other specialist climatological/ hydrological professionals etc, "370 mm of rainfall" simply wouldn't mean a thing to the man in the street ... -- Stephen Burt Stratfield Mortimer |

I assume that the 142.6 is up there in the top 10 even before we consider the 246.6! Richard To get a place in the Top 10 all-time British Isles rainfall amounts, even when looking at strictly 0900-0900 rainday totals, the threshold is just over 200 mm ... I prepared a list of the known and accepted '200 mm in a day' falls for my paper on the Boscastle storm, which appeared in Weather in August 2005. -- Stephen Burt Stratfield Mortimer, Berkshire |

I quite liked the Independent's attempt this morning - a metric ruler down the right edge of the front page with the 24hr total of 314mm at the top and labels for the previous record and the monthly average. -- Graham P Davis, Bracknell, Berks., UK.

It is not surprising then that they are reporting it as a once in a thousand years event. Let's face it, most Brits don't know what 370 mm is, and blame decimalistionl on the EC. When is some one going to say that 370 mm is one foot two and a half inches? or even over a third of a metre, which every one knows is a yard? Meanwhile in Australia, Sydney is being threatened by bush fires, and in Melbourne the police are telling motorists to drive carefully in the heavy rain! It seems that climate change does not mean everywhere gets warmer, just that everywhere the weather is even more chaotic. Cheers, Alastair. |
