I’ve looked at clouds…..

12 new cloud types gain recognition in the International Cloud Atlas

Volutus (roll clouds) and Asperatas (wave like bases) are two of the new additions. http://www.bbc.co.uk/news/science-environment-39351843

The new version of this important reference work is now available online.


Of particular interest is the comment of BBC meteorologist John Hammond.

“It’s one example of how crucial knowledge of cloud physics is – it’s not just an aesthetic, our knowledge of clouds is still fairly limited.”

Given the significance of clouds in the dynamics of the atmosphere and hence temperatures the ‘limited knowledge’ has significant implications for our understanding, and our models, of temperature changes.
