Comments on: A new type of cloud? http://blogs.roanoke.com/rtblogs/weatherjournal/2009/07/02/a-new-type-of-cloud/ Kevin works the copy desk for The Roanoke Times and is its principal weather geek, offering weather reporting training classes to reporters and advising the newsroom on upcoming weather stories.

However, I think the turbulence they suspect causes the undulations is just as valid as the turbulence that causes, say, roll clouds. I also think pilots would want to know if they were approaching, or esp. landing or taking off, under those things. I'll be curious to hear how the World Meteorological Organization reacts after studying this. The pics are awesome, though!

"LeMone agreed that clouds are a "big unknown" in climate change, mostly because climate-change models do not provide a high-enough resolution to determine what clouds' impacts will be on a changing world." Don't know whether either cloud picture qualifies as a new type; however the above quote from the second link is a huge chink in the global warming 'we're all gonna die' scenario. Clouds are binary in global climate models (GLM). IIRC...the GLM grid spacing is 250 km (155 sm). Each box on the grid covers ~24K sq. miles It's either cloud-filled or cloud-free. Not very a compelling representation of the atmosphere. "...the humble cloud is seen as a "wild card" in climate-change prediction, Pretor-Pinney said.
