Amazing Clouds23rd May' 2009
Again in the photos appear a strange kind of clouds, but these - most strange. They were awarded the title Asperatus. After the initial classification was made in 1953, this form of clouds is indeed something new.
Experts at the Royal Meteorological Society are now attempting to make it official by naming it 'Asperatus' after the Latin word for 'rough'.
If they are successful, it would be the first variety of cloud formation to be given a new label in over half a century.
'It is a bit like looking at the surface of a choppy sea from below,' said Gavin Pretor-Pinney, founder of the Cloud Appreciation Society, who identified the cloud from photographs sent in by members.
'They are quite dark structures so there must be a lot of water vapour condensing in the cloud.'
