The frequency of extreme rainfall in the UK may be increasing, according to analysis by the Met Office.

Statistics show that days of particularly heavy rainfall have become more common since 1960.

The analysis is still preliminary, but the apparent trend mirrors increases in extreme rain seen in other parts of the world.

It comes as the Met Office prepares to reveal whether 2012 has been the wettest year on record in the UK.

The study into extreme rain is based on statistics from the National Climate Information Centre, the UK’s official climate record.

Extreme rain is defined as the sort of downpour you would expect once in 100 days.

There are big swings in rainfall from year to year, but the overall trend is upwards since 1960. Last year, for instance, extreme rain fell around once every 70 days.

The phenomenon of more frequent downpours has already been noted elsewhere, particularly in China and India.

Scientists say that as the world has warmed by 0.7C, the atmosphere is able to hold 4% more moisture, which means more potential rain.

The change in the UK trend is slight, but if the trend is confirmed it will clearly increase the risk of flooding.

This year is already the wettest in England’s recorded history. And a series of downpours in late November brought one of the wettest weeks in the last 50 years, causing major disruption.

Professor Julia Slingo, chief scientist at the Met Office, said the preliminary analysis needed further research but was potentially significant.

“We have always seen a great deal of variability in UK extreme rainfall because our weather patterns are constantly changing, but this analysis suggests we are seeing a shift in our rainfall behaviour,” she said.

“There’s evidence to say we are getting slightly more rain in total, but more importantly it may be falling in more intense bursts – which can increase the risk of flooding.

“It’s essential we look at how this may impact our rainfall patterns going forward over the next decade and beyond, so we can advise on the frequency of extreme weather in the future and the potential for more surface and river flooding.

“This will help inform decision-making about the need for future resilience both here in the UK and globally.”

The Met Office no longer publish a seasonal forecast and will not speculate on whether 2013 will produce frequent extreme rain. The immediate forecast however is for more stable weather.

basically the wettest year in about 100 for the UK..the shills are working feverishly to find a way to explain it..”extreme” rainfall is the answer..its not rain or heavy rain..its extreme rain.. because as the world heats up and we get more droughts? we get more rain..yeah..thats how it works..

  1. Well I sure hope they put it on the ‘terrorist’ list, especially because all of those patsy marshmallows pretending to be leaders, may actually ‘melt’ one day. This has got to be the motherlode threat against all of them!

  2. Not to mention the “coincidence” of massive chemtrailing activity over the UK.. I mean the scale of operation is enourmous, and then there’s always induced rain afterwards

  3. What’s the difference between extreme and heavy rain? LOL
