Altostratus or Stratus?
What actually is this grey I see above me?? Is it a cloud? or has the sky changed colour and my world forever changed to grey?
This year I’ve had plenty of hours to wonder about the grey sky and found out there are many different varieties. However, according to the book, The Cloudspotter’s Guide by Gavin Pretor-Pinney, the most boring cloud (above) is likely to be the Altostratus Cloud.
'Altostratus are mid-level layers of grey cloud, which are either featureless or fibrous in appearance, typically extended over and area of several thousand square miles. Usually composed of both water droplets and ice crystals. Typical altitude; 6,500-23,000 ft.'
Sounds bang on, but- warning- the Altostratus can also be confused with a low-level Stratus, Cirro- or Nimbostratus.
Regardless of type of Stratus cloud, to me it look like a giant Softbox, and it feels like it just fell over and hit me in my head!!
