Possible disruption: Severe Gales & Volcanic ash

Paul Hudson | 14:12 UK time, Monday, 23 May 2011


An unusually deep area of low pressure for the time of year is battering parts of Northern Britain at the moment. The highest gust recorded so far is 90mph at Belmullet in Northern Ireland.

The Met office have yellow and Amber warnings in force until midnight tonight, shown below. The Amber area shows where the highest risk of disruption due to severe gales is, with the yellow area a lower level of warning.

For Yorkshire, generally gusts will be 50-60mph, with the risk of gusts reaching 70mph in more exposed areas put at 30%.


Following the eruption of the Icelandic volcano, there will be a lot of nervous holidaymakers across the UK as the Spring bank half term holiday approaches, with fresh memories of the disruption faced in Spring last year.

Unfortunately, weather patterns do not inspire confidence.

Scottish airspace could be affected later tonight.

The main risk is then from Wednesday night onwards, as upper level winds start to drag ash southeastwards across other parts of the UK.

If wind projections stay the same Leeds Bradford, Robin Hood, Manchester and Humberside airports, amongst others, could be at risk from possible disruption towards the end of the week, depending on the concentration of the ash in the atmosphere at that time.

The chart below shows wind arrows at the 20,000 ft flight level originating from the Iceland area and travelling across parts of the UK at 7am on Thursday morning.

There will be further updates on twitter @Hudsonweather

    Not again. Its enough to put you off flying for good.

    We were told that heavy rain was a sign of global warming, now we have had a prolonged spell of very dry weather, people are now saying that is a sign of global warming. I would say that weather is very much like "spirit", you can't control it and it will surprise you. Does anybody remember the extreme wind in Sheffield in the early 1960's that caused a national distaster and damaged a massive number of properties?

    The ash could be a real black swan for our summer - some places in Iceland are in perpetual darkness at the moment..that would certainly make things a lot cooler!

    Pingosan. You could be right about the volcanoe having an effect on the temperature of the earth and at the same time reducing air flights. I was really looking forward to three months summer starting from the 1st of June. Then come October, it can be as cold as it likes and snow all winter for all I care. The problem is we all seem to be close to fuel poverty, due to stupid governmental policies in allowing our energy market to be totally un regelated. I think the government should have kept 51% of the shares, to stop foreign ownership and on top of that we are paying for global warming that is caused by God not man.

    No but it made a right mess of my golf score at Wortley last night :)

    nibor25 . . . I can see it now.
    New study claims that climate change will have a catastrophic effect on global golfing averages in the 21st Century. Model predictions show that if recent trends continue, the average scorecard will increase by between 2 - 5 strokes by 2100. Critics of the paper point to inherent biases in the models, and further claim that they ignore the recent democratisation of the game which has lead to a surge in duffers since 1979.
    Skeptical Science report the study confirms a strong correlation with CO2.

    Haha..Absolutely brilliant....It clearly is much worse then we thought. I'm off to see if I can get a grant to do more research, which will of course involve playing golf in various locations around the world.

    There have been some terrific tornadoes in the USA this year, but is this just down to better global communications? When you look back over the last 100 years, it is par for the course for them.

    Icelandic vulcanologists are betting on a fairly short eruption. But with no extended eruption history for this volcano it is hard to totally believe them.

    The ash from this eruption is larger than that of last years soi should fall out over a shorter distance from the column. Time will tell, but there is still plenty of time for the magma properties or available melting ice to change to get a completely different story. Then again this event might stop tomorrow. This is not a prediction.

    I see that the UK Met Office has blotted its copybook again by having no aircraft to actually go and get some density data. Some expensive laser system based in Exeter is not going to measure ash densities over Scotland.

    They used to have a Hercules modified for air sampling, operated out of RAF Boscomb Down. I suppose they got rid of that to get their big computer to run their poor models.

    So come on Met Office, get some real data and start to serve the people who actually pay for your poor performance.

    Possible disruption: Severe Gales & Volcanic ash; yet, no one seems interested in investigating HAARP. Why?
    Did you notice that HAARP (High Frequency Active Auroral Research Program) website was down past 3 weeks. Apparently, it was ordered down by the US Government - purpose unknown. It's back up.
    HAARP’s magnetometer can be used to predict as well as give evidence of a HAARP created earthquake. A magnetometer measures disturbances in the magnetic field in Earth’s upper atmosphere. HAARP was broadcasting a 2.5 Hz frequency (the signature frequency of an earthquake) just before midnight on March 8, 2011. The 2.5 Hz frequency continued to be broadcasted and recorded by the magnetometer for another 10 hours the day of the Japan 9.0 magnitude earthquake. I can't say the events are related; I'm not a scientist, but it sure seems like something demanding investigation, doesn't it?
    By beaming the frequency at a specific trajectory HAARP can trigger an earthquake ANY PLACE ON EARTH. A short burst isn't enough to disturb solid matter (the Earth's crust) so the beam is maintained for hours or days – until - SUCCESS.
    How do we know such a WMD EXISTS?
    The Environmental Modification Convention (ENMOD) prohibits the military or other hostile use of environmental modification techniques. It opened for signature on 18 May 1977 in Geneva and entered into force on 5 October 1978. The Convention bans weather warfare, which is the use of weather modification techniques for the purposes of inducing damage or destruction.
    Evidence from HAARP’s own website reveals that the US government has acted in violation of the ENMOD treaty – use of weather modification techniques (HAARP) for the purposes of inducing damage or destruction. HAARP broadcasting data published on the HAARP website coincided with a number of recent catastrophes such as
    - 2010 Haiti earthquake,
    - 2010 heatwave in Russia,
    - major floodings in 2010 in China and Pakistan and
    - major earthquakes in Haiti and Japan –
    all occurred ON president Obama's WATCH. Would any President direct HAARP against his own people (e.g. Joplin, Missouri)? I hope not, but then again...
