Volcanic Ash, Grímsvötn, Iceland

Who would have believed it just one year on? The weather has indeed been strange and extreme around the world. Even in Scotland we have had storms and extreme winds as a result of a low depression resulting in uprooted trees and lots of damage and yes,  it is less than 4 weeks to the longest day! Summer where art thou? At home we have been without electricity for 29 hours, no heat, no warm food, no internet access and lots of withdrawal symptoms. Minor inconveniences in the big picture of things happening around the  world.
Travel plans have had to be changed as flights from Edinburgh have been cancelled due to the eruption of Grímsvötn in Iceland. Have the airlines learned from last year's chaos? Who knows but, in all honesty, I am not taking any chances. Fingers crossed that flights from London to Antigua won't be delayed!

Observations from satellites of the ash plume.
Meteosat Second generation (MSG)  images are monitoring for the presence of volcanic ash emission in the vicinity of Iceland using infrared data from the Meteosat Second Generation (MSG) satellite. Because cloud particles and volcanic ash particles interact with the infrared radiation in different ways, data at several different wavelengths can be combined to identify the main ash plume, which, when present, would be shown as pink, yellow and orange colours in the images. However, it should be noted that it is only the thicker parts of the plume that are able to be detected by this method. In addition, the ash plume is often masked by overlying high cloud and therefore might not appear in the satellite image.

So instead of flying to London from Edinburgh have spent the night in Gleneagles, driving to Stirling to take the train to London and hopefully flying out tomorrow........... don't count chickens etc! Early morning and no gales! 


Thinking.......red sky at night, shepherds delight, red sky in the morning, shepherd's warning!!!!!
