Does anybody know whether or not Met or any other body would be looking into the changes in weather today given the lack of contrails in the skies?

They did in the US during 9/11 when flights were grounded

Are you saying the planes in the sky change the weather?

Just seen 3 contrails here in donegal (didnt know thats what they were called) heading for america

There was a sudden drop in tempeture when the skys were clear of all air traffic during 9/11.

Yeah, that's the main track of the dust plume. We're not really anywhere near it, but the circulation of air around kicked up dust in proximity to it, over the UK and over the irish sea.

It makes me wonder what happens both to that plume and to new ash if the wind changes as forecast Saturday night. It seems to me, but I'm just a lay person, that if those forecasts panned out there's a high chance that main plume would get pushed down and spread out over most of the british isles. We'd be in much closer proximity to main flow of ash than we were on Thursday.

Anyone have a more informed opinion?

That photo was for yesterday. Here's the latest Hi Res Visible, showing some ash to the east of Scotland and also between England and Belgium. Notice you can also make out those contrails north of Donegal, they would appear to be heading into Belfast.

Yeah, contrails sometimes develop into cirrus clouds which can have a warming effect

sorry mate, looks like her flight has been put back till tomorrow morning. not sure what that means for you, but i'd keep my bags packed us in case anything changes, they seem to change their mind almost every hour or two.

Actually looking at the sat animation it seems those planes are heading west, so probably the ones that left Dublin for New York and Boston around 11

I think Cork flights will probably be grounded again. The IAA warned it might happen and these charts point in that direction too. Indeed these charts have the ash over more southern parts than they might have expected earlier.

Just noticed there has been 4 small earthquakes detected at Eyjafjallajökull between 9 and 11 this morning. Thats more seismic activity for that region in a couple of hours than there has been in the past couple of days.

Could that be significant?



Also, here's the latest update from the Icelandic Met Office :

Ongoing eruption
16.4.2010

The plume from the eruption in Eyjafjallajökull volcano is still ongoing, reaching hights of 4 to 5 kilometers, occasionally reaching higher altitudes.

The plume drifts with north-westerly winds reaching Europe. It has been detected over Norway, Sweden, northwestern Russia, northern Polland, northern Germany, northern France and southern UK .

There is no indication that the ash from the volcano is decreasing and it is predicted that high-level winds will stay north-westerly today.

Closure of airspace over england and wales extended to 7am tomorrow.

Limited operations in northern airspace (Scotland, NI) and opportunities for selective operations out of Newcastle.

Restrictions on Manchester have been reapplied after a few flights this morning.

The cloud of volcanic ash continues to move south through the UK and the eruption in Iceland continues.

Following a review of the latest Met Office information, NATS advises that restrictions preventing flights in controlled airspace over England and Wales will remain in place until 0700 (UK time) tomorrow, Saturday 17 April, at the earliest. From 1900 (UK time) today ATC restrictions will be lifted in a large part of Scottish airspace including Scottish airports, Shetland, Orkneys and also Northern Ireland.

On this basis, North Atlantic traffic can also operate to/from points in this airspace. Please note these arrangements do not mean that all flights will operate. Anyone hoping to travel today or tomorrow should contact their airline before going to the airport.

We are looking for opportunities when the ash cloud moves sufficient for us to enable some flights to operate under individual coordination with ATC. Some aircraft were able to operate at Manchester this morning, although restrictions are now reapplied to Manchester.

We hope there may be some opportunity from the north into Newcastle after 0100 (UK time) tomorrow - Saturday. We will review further Met Office information and at 2030 (UK time) we will advise further arrangements. In general, the situation is dynamic and subject to change.

We continue to work closely with airports, airlines, and the rest of Europe to understand and mitigate the implications of the volcanic eruption.

They're pretty much following the VAAC models precisely. It was pretty easy to predict a reclosure of Manchester based on those earlier.

Interesting little bit of info :

Met Éireann's Evelyn Cusack said high pressure pushed the plume east and it never came over Ireland. She said a change in the winds on Monday or Tuesday could bring it back over the country. However, she said heavy rain in Iceland may wash the particles out of the air before then.

All I can say is that there was light brown dust all my car and my wifes car this morning and it was not there yesterday (because I specifically looked out of interest). When you rub it of, you get a dirty darker brown smudge on your finger.

Have seen/looked at Saharan dust on my car - it was nothing like that.

Something fell out of the sky overnight!

Just checked again and it has slight sparkle to it! Just took close up picture and have emailed to Met E.

The met eireann page updated for today says they expect ash to penetrate into irish airspace from the east and southeast later this afternoon and evening.

The VAAC forecasts seem to also point at risk in the south and south east for later.

I'm slightly surprised the IAA hasn't reapplied restrictions to Cork as a result, but maybe they think they've enough time before there's an ash risk in these parts again.

I was just reading this...

15:34 Reports of dust deposits around Ireland are unlikely to be volcanic ash, warns Met Éireann.

Gerry Murphy says initial indications suggest that this material is not volcanic.

The volcanic ash plume is drifting to the east of the country and it is unlikely that any ash will be deposited here unless it rains.

15:26 However in the UK, scientists say they have confirmed that ash that settled in the Sheffield area is in fact volcanic.

Dr Hywel Jones from Sheffield University's Materials and Engineering Research Institute, spotted the dust on his cycle ride into work.

'We analysed the samples and found they contained silicon and oxygen, calcium, aluminium and sodium, which make up volcanic matter.'

Any idea when Aer Lingus will decide whether to cancel their flights from ireland tomorrow? Specifically flights before 7am.

Cork to Munich??

Have checked aer lingus site on and off over the past few hours but no word of tomorrow yet.

Su Campu

Looking at the Mace Head live data for today there is a huge increase particle concentration in the last couple of hours. Not sure whether this has anything to do with the ash or if it's just the diurnal increase that takes place at low tide when the concentration of iodide aersols from the seaweed increases on exposure to sunlight.

Both the particle size and concentrations are around 100 times greater than earlier in the day.

From the data and predictions of ash so far, I'd say not

Hmmm.

16:31 There have been reports of 'unusual dust' deposits from many parts of the west and the northwest this afternoon.

Met Éireann says it is unlikely to be volcanic ash - but one of the country's leading climate change experts says some of the deposits he has seen in Galway may be linked to the eruptions in Iceland

It's slightly disconcerting that there could be ash that far west while risk models have given Ireland the all clear I guess our met office doesn't have surveillance planes and the like that could take samples...

I think it's possible - looking at the satellite loop 'wisps' of cloud are drifting southwards over the west and northwest. It looks similar to what's over the North Sea too.

Well this is a kind of big escalation of things:

17:11 Ryanair has confirmed that based on current meteorological forecasts, and the continuing emission of volcanic ash into the atmosphere over Iceland, it has decided to cancel all scheduled flights to/from the UK, Ireland, Denmark, Finland, Norway, Sweden, Belgium, Holland, Northern France, Northern Germany, Poland and the Baltic States until 1300hrs on Monday 19 April.

This could change I guess, but that seems the most conservative action I've seen taken by any airline, stretching out into Monday!

edit - here's a direct link: they're doing this so that all passengers potentially affected have as much notice as possible to rebook on flights later in the week at no extra cost. Makes sense I guess, as someone meant to be travelling with Aer Lingus on Sunday to London, the short notice and lack of notice on how this is developing is rather annoying.
