|In case you were abroad over Christmas and the New Year, getting away from the weather no doubt, you may have missed the fact that 2012 was the second wettest year on record for the UK. I wonít indulge you in those details as the majority of you, those who stayed home, will well know the national facts. But here I would like to throw a little local perspective on the matter.
Rainfall figures are freely available for UKís second wettest year on record in addition to those for Walesís third wettest, Scotland 17th wettest and Northern Ireland 40th wettest but details of Englandís wettest on record, in deed thatís what it was, are more elusive. Here I will localize it even more and throw light on Uplymeís probably wettest year. Ever?.
Rainfall for 2012 measured on a Met Office gauge at Rhode Hill was 1420.4 mm against a yearly average for this millennium of 992.4 mm. November was the wettest month of the year with 207.3 mm Ė 183.4 % of the average. But the wettest in respect of the amount of rainfall above the average for the month was June with 189.4 mm or 341.5% of the average for the month. Two other months with double the expected amount of rain were April and July with 165.7 mm (258.3%) and 186.6 mm (228.3%) respectively. July was also the wettest July since my records began at Rhode Hill.
Three years ago I posted this on the forum, http://uplyme.com/debate/viewtopic.php?t=598&highlight=rain and there refered to the increasingly wet Julys and illustrated this with a chart http://rhodehillgardens.co.uk/july.gif I can now offer another chart that shows a trend to a change in the balance of the rainfall throughout the year http://rhodehillgardens.co.uk/ratio.gif .
2012 was the first year that my records show that the Ďsummerí months (April through to September) were wetter than those of the winter (the other six months of 2012)
A graphic way of looking at the change from drought to flood that we saw in 2012 can be seen on another chart http://rhodehillgardens.co.uk/rolling.gif There we were in early April with rainfall for the previous 12 months close to a probable all time low of 639 mm when it bagan to rain. Looking at the chart you may say hey 2012 wasnít the wettest year as the chart shows peaks above 1500 mm in early 2001. This does show how arbitrary it is as to what you determine is a year. Although rainfall for the 12 months to 14 December 2000 was 1491.35 mm and that for 22 March 2001 was 1535.05 mm that for the end of the year on 31 December 2000 was 1397.98 mm.
We no longer hear talk from the Met Office of barbecue summers. Neither do they anymore refer to the future weather that climate change will bring as hot dry summers and mild wet winters. They seem to have gradually come round to the fact that warmer air holds more moisture and since just before Christmas it as been their main message regarding our future climate that this moisture will be shed from the atmosphere as rain.
If you wish to be bored even more out of your mind then there is endless amounts of rainfall data on my website http://rhodehillgardens.co.uk/rain.html
It's later than you think
