Clear Blue Sky

Lao · April 17, 2010

What a fantastic sunny day today around Merseyland.

What really struck me though was the crystal clear blue sky. Not a single cloud, but more to the point, not a single vapour trail. Usually there will be about 4 or 5 planes about in the sky at any one time, and scores of vapour trails all over.

So this particularly lovely day has been a pleasant by-product of the volcanic ash cloud causing flight cancellations.

It made me wonder. How much of the cloud cover on a normal day is actually caused by air traffic?

Planes out!

High pressure zone (anticyclone) causing the sunny clear weather, means the ash ain't dispersing......... its actually bringing more ash down towards the UK..........

Oh and you may notice the large BLUE front moving towards the Blackburn area....... returning to Merseyside by the evening!

there was a programme about the hazing from vapour trails, or lack of it following 9/11 when all the planes in the u.s. were grounded, they commented on how much clearer the sky was, as when the trails start to disperse they actually spread and cause more shading of the globe.
Following 9/11 was the first time that they have been able to do the study due to planes flying the rest of the time
