    So with the lack of con trails, will it mean the temp will rise? :D

    Wierd not seeing any trails usually there are at least 1 every minute and sometimes 5 or 6.

    Not unusual in this type of set up. Lack of contrails is a good signal that the air is very dry at higher levels. The more persistent the contrail, the more chance it will rain :)

    The Irish Aviation Authority has warned that the disruption to flights from the volcanic ash cloud could last days.

    Well, that's the summer gone.

    From the IrishTimes: http://www.irishtimes.com/newspaper/breaking/2010/0415/breaking16.html
    How volcano ash can affect the weather

    Thu, Apr 15, 2010

    Volcanic eruptions sending ash and gas into the atmosphere can have a massive effect on the weather.

    In 1815 a huge eruption on the Indonesian island of Sumbawa caused freak weather conditions throughout the world.

    Mount Tambora spewed out massive amounts of sulphur dioxide which combined with water vapour to form a sulphuric acid mist that reflected sunlight away from the earth.

    That caused such a drop in temperatures that 1816 became known as “the year with no summer”.

    Crops failed due to low daytime temperatures, late frosts and abnormally high rainfall, provoking food riots, famine and disease.

    In Ireland, rain fell on 142 days that summer and across France the grape harvest was virtually non-existent.

    In North America there was snow in June and lakes and rivers froze as far south as Pennsylvania during July and August.

    It followed a smaller eruption in Iceland just over 30 years earlier that caused a thick fog of gas virtually wiping out the summer of 1783 across much of Europe and North America.

    American statesman and amateur meteorologist Benjamin Franklin wrote of a “constant fog” over Europe and North America that year.
    Forecasters say the cloud of ash drifting the across the UK at the moment will not produce anything so momentous but it could still affect the weather.

    Brendan Jones, a forecaster with MeteoGroup, the weather arm of the Press Association, said: “If you look back in history there have been some periods where the weather has been changed by big volcanic eruptions like Mount Tambora and Mount St Helen's.

    “They have been proved to lower temperatures. There is so much ash in the atmosphere that it reduces the amount of sunlight getting to the ground," he said. "If the ash remains in the atmosphere for weeks or months it can reduce temperatures slightly but we are talking about fractions of degrees.”

    In fact the most noticeable result could be more spectacular sunsets as the sun’s rays reflect off the ash cloud.

    Mr Jones said: “The sunset lights up the underside of the ash and you could see a glow from the ash in the sky.”

    The eruption of Eyjafjallajokull in Iceland, which has sent this cloud of ash into the sky, is the first in nearly 200 years and geophysicists fear it could trigger a much larger explosion of nearby Mount Katla.

    Katla is described as “enormously powerful”, and because it lies under a glacier its eruption would cause a huge glacial outburst flood and could spread its shadow over a much larger area.

    Met Éireann said today a new phase of the Eyjafjallajökull eruption started around midnight and volcanic ash has been observed in British airspace. It said its Aviation Services Division has warnings in place for the ash to penetrate Irish airspace to the east and southeast this afternoon and evening.

    LAtest RGB satellite animations show the high level plume dying down a bit over the last couple of hours, though that could mean nothing if it erupts again.

    Nothing new there lol

    Is there any chance we will see much of the ash on the west side of ireland?
    Here in dongeal we are probably nearest to iceland but met eireann said ash would be on east and south east I think, wind direction i guess :(

  • Registered Users, Registered Users 2 Posts: 7,175 ✭✭✭pauldry


    There wont be ash in the North or West of Ireland and only on the South and East Coasts it seems now.


  • Registered Users, Registered Users 2 Posts: 5,565 ✭✭✭Pangea


    Yes thanks, today anyways there will be none ,but that could all change in the coming days.

    Forecast ash plume from DMI:

    dreameu_ani.gif

    Ash plume is actually low to mid level based at the moment, but an approaching low towards Iceland could lift further plumes higher which would cause a wider distribution.


  • Closed Accounts Posts: 29 mccarn22


    Im very interested in this for some reason.. I should oh became a geologist there is a very supicious "fog" looming around the Dublin region as of now.... perhaps a coincidence or is this actually ash cloud fallout??

    Geologists are saying that this eruption may be the beginning of worse to come... perhaps 2012 is upon us? Over 100,000 flights cancelled across Ireland, England and Northern Europe... there are also delays and more cancelations expected tomorrow...

    Nil it looks like.

    Apparently they can smell the sulphur in down town Bergen. Norway is directly in the track of this.

    On a positive note, volcanic ash in the atmosphere can increase the chance of thunderstorms! Spontaneous and violent thunderstorms, with an unusually strong redness in the lightning, were noted all across Europe during the "Laki Haze" in the late 1780's.

    im ****ing ****tin' now.... haha... but im still very much excited at the same time.. there is a break in the clouds across Dublin 9 now... so perhaps its not "fog" instead the windows that im looking out of are just dirty giving it the elusion that its foggy outside ha

    hopefully some good will come from this, that being next winter is a cold one:p

    So the last time Eyjafjallajökull erupted, it went on for about 2 years & the last three times it erupted it 'directly preceded a major eruption in the nearby subglacial volcano, Katla'.... :eek:


  • Closed Accounts Posts: 5,234 ✭✭✭thetonynator


    this is nearly as exciting as the snow threads . . .but with a higher liklihood of death unfortunately . . . :(

    I was just about to post the same comment! I'm now stuck on the internet most of the day! :D

    Risk of death unlikely imho. Icelanders have been evacuated from affected areas and obvioulsy aviation authorities are very cautious.

    Risk of another s**te summer though is not appealing! :(

    Depends on how long the eruption lasts and where the weather conditions force the ash to go. The last time it erupted it went on for about 2 years but that doesnt mean it will happen like that this time.

    You mightn't get anything but there may be a couple of feet of ash on the hill behind you in the morning? ;)


  • Registered Users, Registered Users 2 Posts: 16,958 ✭✭✭✭nacho libre


    can someone inform the aviation authorities this is a non event, and therefore there is no need for updates and warnings, seeing as it's not effecting Coleraine:p

    Any chance of a few inches of ash in tipperary, any chance lads. Do any of the ash experts think it will last long:D:D


    ahhh, I'll get my coat:rolleyes:

    Met Eireann have this article up on their site now :


    Volcanic Ash Advisory

    15 April 2010

    A new phase of the Eyjafjallajökull eruption in Iceland started during the 14th of April, where melt penetrated its way to the central crater beneath the glacier. Bad weather has been making visual observations difficult today but the plume of volcanic ash can be clearly followed on the weather satellite images.

    Volcanic_ash_15apr.jpg

    Volcanic ash has been observed in British airspace and the Aviation Services Division in Met Eireann have issued warnings of the ash penetrating Irish airspace to the east and southeast of the country this afternoon and evening.

    The meteorological situation at present is that there is an anticyclone centred to the northwest of Ireland. The airflow is anticlockwise around an anticyclone, and thus the air is being steered down from Iceland to Scotland, down across England, and back around towards the southeast of Ireland.

    Our weather models are indicating that it is going to remain dry over the next couple of days so we do not expect any significant surface deposition of ash in the short term. Ash and dust normally reach the surface through being washed out of the atmosphere by rain.

    Next week the airflow will be more directly from Iceland to Ireland and the weather forecasts indicate that there will be precipitation so, if the eruptions continue, it is possible that there will be deposition at that stage.

    Unfortunaey it will be wet ash and it won't stick. The sleet of the ash world, 'slash' is a good term for it.
