Icelandic Volcano - Weather effects?

[Hell27]

Hi all, is there any meteorologist types out there? I was wondering if the plume of Volcanic Ash having an effect on the climate of GB at the moment - it's been very cloudy recently, could the volcano factor into this?

It's the plume.

The cloud above most of the UK is frontal weather not 'volcanic cloud cover'.





Here is the predicted extent of the volcanic ash cloud for 19:00 Uk time tonight.



The cloudy frontal weather spreading southwards across the U.K. brings the volcanic ash from the north. Remember last week when the Volcanic ash cloud was at its predicted worst, most of the U.K. was experiencing clear skies as viewed from the ground.

There's a chance that, if enough material and sulphur dioxide gets high up in the atmosphere there could be a positive contribution to global average temperatures in that they could steady or even decrease a little. Global cooling has been noted after several previous eruptions. If Katla (the bigger volcano next to Eyjafjallajökull) erupts too there's almost certain to be an effect on global climate.

Is this your first time in England?

When the airports were closed last month, we had about 2 weeks unbroken sunshine...

That was because it was higher up then. It's now falling to viewable levels.

Are you suggesting the VA cloud was higher up before and that somehow made it clearer or more sunny as seen from the ground? If the cloud is the same density but simply higher up?

The cloudy weather we are experiencing is simply common frontal weather and not Volcanic ash. Check the met office charts. The VA cloud was at the same 0 - 20,000 ft extent all the way through the first eruptions and isn't actually over most of the U.K. at the moment.

It did leave some nice landscape for us to visit afterwards though didn't it ?
