Winter deluge

Postby Len Wood » 2013 Dec 21, 23:44

Have had 87 mm here in the 9 days since the winter drought was broken.

Looking at the forecast for the rest of December it looks as though it will not be
difficult to beat the 119 mm December average.

The deluge began on 13 Dec.
Rain everyday since.
That is 231 mm in 24 days.

I am wondering if the 277 mm of Dec 2012 recorded here is going to be beaten.

Since the 13th of December:

164 mm has fallen (to 18:00 on the 5th Jan)
Only 1 day without rain (28th)
But 4 days had <1.0 mm

To compensate somewhat there has been 63 hours of sunshine in that time, which isn't too bad given the time of year.

Rain eased off, temperature rising. Now 11.8°C at 18:30.

Out here in the relatively dry east of Cumbria my one month total for 9.12.13. - 8.1.14. stands at:

346.6 mm

that is more than the 317.2 mm that I had in the wettest month in recorded history in Cumbria, ie: Nov' 2009

Here in Berkshire, the total rainfall for the 27 days to 8 January stands at 194.5 mm, 296% of normal for the period, and the wettest 27 day period at any time of year since January 1915 on an unbroken and homogenous local daily record back to 1910. The fall in December-January 1915 was only 1 mm (0.5%) higher than this year's total.

Extending the local record back to 1862, on a monthly basis 1862-1909, in 152 years there have been only four calendar months to exceed 180 mm here, and only one previously > 190 mm. This year's fall will, of course, be split across December and January.

So now a comparison can be made with the record wet 31 days of Dec 2012 which gave 277 mm here.
The latest 31 days, 13 Dec 2013 to 12 Jan 2014, have given 253.1 mm.

And the rain is continuing according to the forecast.
I have not had a rainless day since 12 Dec 2013.

... Over that same period, rainfall totals at West Moors = 293.2 mm and at nearby Hurn = 296.2 mm.

Looking at the Hurn record (MetO web site/starts 1957), then the wettest /whole calendar month/ is that of October 1960 (258.9mm), so the recent 31-day total would exceed that comfortably; however, I note that October 1960 was bracketed by two reasonably wet months, so it's possible that a 31-day total similar to our recent experience was recorded over a month-junction.

In Penzance, over the same period, 263.9mm

There have been longer sustained wet periods. November & December 2002 saw a staggering 543.8mm! There was a lot of flooding locally. This year the only flooding has been by the sea.
