Weather

The fine spell of late summer weather which has seen temperatures today rise to a new September record of 29.4C at Wattisham in Suffolk (beating their previous record set in 1973) will come to an abrupt end in the next 24 hours, and could lead to localised flooding in places.

 

It’s a text book break down of the weather, as cool air from the north meets very warm air from the near continent, resulting in a rapid destabilisation of the atmosphere.

 

The contrast in temperatures across the UK is dramatic, with just 12C (54F) recorded at Aboyne in Aberdeenshire this afternoon, compared with 30C (86F) in Kent.

 

And under the right atmospheric conditions a temperature contrast like this can lead to copious amounts of rain, with parts of Northern England in the highest risk area, together with North Wales.

 

With much of the ground still firm following the dry summer, rapid run-off could lead to localised flooding.

 

Current estimates suggest that 25mm (1 inch) of rain is likely across a wide area, but some spots may see 50mm (2 inches) – or more – during Friday and into Saturday morning.

 

With temperatures in our region struggling to get above 15C (59F) on Friday with a brisk northerly wind, it really will feel like autumn has arrived.

    "The 60% ice cover figure was posted on Climate Depot and authenticated."

    Did you post a link to the authentication?

    I could see some reference to the topic but it just seemed to be links to the Daily Mail article.

    It seems that you have to be a twit to be an up to date scientist nowadays!

    Forgive an old chap if the expression is somewhat incorrect, but it does have a ring about it.

    I asked the question of the website, and got a reply:

    'Thanks for the email. We don't have the facility to publish the winning question on the site until we physically record a video response. We do however publish the winning question immediately on our social media channels Twitter @myclimateandme and Facebook \myclimateandme

    For your information the winning question was 'Is 30 year warming subject to a 60 year cycle?''

    "I am not sure I can cope with yet another version of the extent figure!"

    Same here, that's why I stick with Masie, I like the CSV output of data for all the areas.

    Further confirmation that this years ice started off thin but still a lot of first year appears to have made it through:-

    "Esa's Cryosat mission observes continuing Arctic winter ice decline"

    http://www.bbc.co.uk/news/science-environment-23964372

    So maybe its not "all about September 2014" will it first be all about March 2014?

    As always only time will tell

    "I have been using:-

    http://nsidc.org/data/masie/"

    The total NH extent figure from that source seems slightly different to the normal NSIDC figure.

    I am not sure I can cope with yet another version of the extent figure!

    Nothing to date.

    Had a quick look at the site, nothing there that I can see. Though I did watch the featured "The British Energy Challenge" video, quite informative, only 5 mins, might seem longer.

    Thanks for that.

    This makes it all the more bewildering. Why is he comparing two dates in August separated by nearly two weeks against one another, and how does he arrive at the 60% figure?

    So many questions!

    I'd be interested in any response you get from David Rose.
