Weather Talk
By Mark Vogan

Discussing the Icelandic Eruption, it’s scale and effect on Britain and NW Europe

To provide people here on the ground with peace of mind, this ash is so high up (at or above 20,000ft), we down here will experience literally no effect thanks to high pressure system which has ultimately capped or created an inversion between us at the lowest 5-10,000ft above earth’s surface, above that level, there will likely be ash blowing out of the northwest across the British Isles and over mainland Europe. Those with lung issues have been advised to keep medication close by but only as a precautionary measure.

What’s amazing to me is that this “invisible” ash cloud which we can’t see is creating such vast disruption to air travel to millions of people and across a great distance.. Normally airports will suffer a huge log of cancelled flights, even airport closures due to most commonly, snowstorms or some other extreme “weather” event, but because of volcanic ash?, like this past winter here in Scotland, this is a first and a first for basically the entire British Isles in living memory. All this, brings to mind just how much our planet and it’s people depend upon this type of transport and all forms of transport which at one time didn’t exist. The best of it is, this tyep of event has occured before, probably many times and probably a whole lot worse than this.. The big difference is that we didn’t have aircraft back during the last time this event likely occured… Even 50 years ago, if this had of occured back then, during even that short period of history, we didn’t have anywhere close to the amount of aircraft we have today or the demand. This is another example of the “what if” scenario, the doomsday scenario which organisations train and plan for for many years… They have been planning for this for many years in Iceland as well as the Met Office, the airports, geologists and other groups for this exact event here in Britain. The government plan for events in which the general public don’t know their training and preparing for… This is one of those events which many have perhaps said, oh, what if this was to happen and this time, is has…

Will the complete absense of aircraft over Britain and much of northwest Europe reduce pollution and effect weather or more importantly temperature here at the surface?

After 9-11 I remember reading an article released about the effect the total absense of air traffic over US airspace had. The temperatures at ground level were said to have been warmer by day and cooler at night. The film of cloud created by thousands of airplanes streaking through the skies at any one time, keeps daytime heat above this film created by planes, by night is usually stays warmer, but the reverse happened the the absense of this aircraft film covering US airspace and therefore warmer days and cooler nights were said to have occured. It’s amazing to think about just how much effect aircraft, numbered in their thousnads and cruising at varying levels of the atmosphere above British airspace has on, simply the temperature.. We may find a similar scenario like the Americans did after 9-11 with a warmer day and cooler night, particularly so, since we have high pressure in control of our atmosphere and there is good periods of sunshine in many areas at the moment. This high pressure cell may also be the saving grace to not having more effect from this ash down at lower levels which could effect humans.

What will be interesting is just how long could this last and what next?

    >Good article! It's possible that the eruptions could continue for some time – I've read that Eyjafjallajokull erupted – on and off – from 1821 to 1823, so it's possible the disruption could go on for some months (years?) to come. Potentially this could have a massive impact on travel/tourism/business, definitely something to keep an eye on.
