    Is anyone else finding netweather 7/10 day forecasts a bit inaccurate these days or is it just me?

     

    Hmmm.... that big cyclops thing on meteociel just now for  monday / tuesday doesn't look any more tightly packed than some of the lows we've had here in the past month, such as last midweek or late november.... only bigger and thus "spreadin' the love" across a larger area, perhaps ?

     

    It does actually look that bad I agree.

    Bit of a learning curve for me here - 932 is obviously *very* low (record is 927, mid-19th century Perthshire, iirc?)BUT if it drops gradually, ie those lines are not packed bang-on-top-of each other, then it's not too dangerously stormy. It's when it drops 40mB in a few hours that you get bombogenesis, yes? And that's A Bad Thing, yes?And at present although this looks really windy and blowy for the 24th, it isn't that dramatic sudden drop, so we may yet get away with it just being very windy rather than huge swirling gusting winds ripping everything to pieces?

     

    Well this LP goes from Svalbard to Morocco with the centre at 940 mB, if it went from Iceland to Ireland, say sandwiched in with a high pressure somewhere then you'd get a huge gradient, tight isobars, and we end up in Denmark or Norway!  I'm sure someone will explain it better than me!

    Hah! Internet must have died briefly just after 06.00 when the worst gusts began (through until 07.30). When I got downstairs I discovered the problem of no data transmission to my laptop Weather Program although data was reaching the Control Panel just no onward wireless or internet transmission. Hard restart of Control Panel fixed that but data was lost sadly.

     

    Went fairly calm here at 09.30 so I guess the worst is over. Two trees down beside us with many more branches down also.

     

    Both the Friarton and Tay Bridges were closed so Perth centre is bottle-necked as it is the only way to and from Dundee just now. Glad I am off today.

     

    Strongest gust closest to here was 106mph at Glen Ogle in Stirlingshire.

     

    101 mph recorded on the Tay Bridge.

    See below. Just water, denatured ethanol (sorry HC, no drinking unless you want to go blind) and a couple of drops of fairy liquid per 2 L prepared wash. You can buy denatured ethanol online. I found this just quickly on amazon.  Would make 17 L of -10 for ~£24. Or roughly twice as much for -5 C. Could well be better deals with a bit of searching. http://www.amazon.co.uk/Denatured-Ethanol-B100-Specific-Alcohol/dp/B00EIFTW0W/ref=sr_1_6?ie=UTF8&qid=1385974610&sr=8-6&keywords=denatured+alcohol You can make up a strong mix, e.g. 50/50 for screen de-icing with a spray bottle. Don't use pure as it could slowly damage rubber seals / wiper blades.

    I switched from using ethanol in my homemade screenwash to methanol, you need a lower percentage for the same freezing point and it gets rid of the salt stains off the windscreen better. Plus you don't get that wiff of jakie every time you hit the screenwash.

    The mild start to October continues (many stations running +4c or more above average so far). 12c here at the moment with hazy sun, temps should get into the 17/18c range again today in NE Fife. I'm enjoying the late season warmth while we can!

     

    Scrape the car in the morning, shorts and t-shirt in the afternoon kind of weather!

    Is it my imagination or does 5C feel a lot colding in September than in April? I dislike this.

    Yeah I'll echo feelings of blessed relief at the lack of tourists & their sodding campervans. Very heavy blustery showers on the north coast since the middle of yesterday, currently almost continuous. Doesn't feel that cold although it certainly isn't mild any more.  Haven't had a day like this since the winter!

    You should see the road to St Andrews on a holiday weekend or sunny day, can take 20 minutes just to get from my house to outside Cupar.

    Sure is Hiya! Eventually the oceans 'catch up' with themselves but anomalous heights run all over our oceans. if you think about tidal bulges dragged by the moon or low versus high pressure over areas of the ocean you'll get what I mean? Certain regions are seeing highr rates of sea level rise than others but , obviously, as sea levels rise all the ocean levels rise!

    On a purely experimental scientific basis, which I am suitably qualified to comment on...I am highly sceptical that such measurements are accurate in extreme localities. You would need to measure for a very long time. It strikes me that there are so many errors introduced into the measurement it would be very hard to verify. You could just as easily be measuring the sea bed rising due to plate shift for example, or increased run off from the land. I also think the "catch up" probably doesn't take very long, days at the longest.Probably if there is a paper attached to this it is worded in such a cautious way and this is likely yet another example of tentitive scientific result reported as hard fact by the media.

    What are the actual figures for this acidification which is making the Ocean 'toxic'.

    It seems a mischievously worded piece making sweeping statements such as that but read it properly and it's the usual 'threatens' and 'coulds'

    The play on 'acid' alone is pure hyperbole since they mean slightly less alkaline in fact

    Also what is this 'soaring Arctic CO2' in the title about.

    Has it soared significantly more than the same gradual climb observed elsewhere?

    In short it sounds like another soundbite propaganda piece to be spread around the net by the converted, purpose being what exactly?

    To frighten schoolchildren to the cause presumably, because anyone with any maturity can see it for what it is.

    It's just more of the endless negativity and carping that the alarmists are so fond of.

     

     

    Quoting a percentage increase in acidity did make me raise an eyebrow. This isn't normal scientific practice, but since pH is a log scale it doesn't lend itself to pin up headline numbers, in addition they probably want things to increase rather than decrease for PR reasons. "35% increase in acidity" is just so much more sellable to the public than "a decrease in pH from [ca] pH 8.2 to pH 8.05".

    Sea level is rising -- and at an accelerating rate -- especially along the U.S. East Coast and Gulf of Mexico.

    On April 17, 2013, the Union of Concerned Scientists convened a multi-state roundtable of city and county planners and the Army Corps of Engineers to discuss strategies being considered or actively being implemented to protect coastal communities from the increasing risks of rising seas and storm surges along U.S. coastlines.

    This segment from the Weather Channel highlights the roundtable event and describes the growing risks of sea level rise, which you can learn more about in this UCS sea level rise infographic (http://www.ucsusa.org/sealevelrise) and fact sheet (http://www.ucsusa.org/sealevelrisesci...).

     

    Is it really possible for sea level to rise is one specific place?
