A picture of "cloud streets" over the east coast of the US taken from a satellite. These are all the parallel lines of cloud starting over the Atlantic and running south-east. You can have a look at the NASA page here. They have happened because cold air has blown over the warm sea but there is a warmer air above those two layers. Convection gets set up in the bottom two layers but trapped when it hits the top layer. These convective cells seem to set up in long parallel tubes. This means we get shallow cloud (at the top of the second layer) along the side of the tube where the air has risen from the seaAnd for those of you with a sharp eye - yes we have just learned how to put images in out posts New episode recorded - post it soon.

Join us as we take to the skies in our first episode of 2011, exploring the aircraft scientists use to study the atmosphere. Dr. Keith Bower regales us with tales of his adventures in the high clouds, looking back at his 12 years of science flying. Will and Jen take us on board the UK research aircraft, the Facility for Atmospheric Airborne Measurements BAe-146, and as always, we cover the recent weather and climate news.Featuring: Grant Allen, Gavin McMeeking, Will Morgan, Jennifer Muller and Niall RobinsonInterviewee: Dr. Keith BowerProduction: Gavin McMeekingMore info:Check out these links for pictures and to learn more about some of the aircraft we discuss in this episode: Dournier 228, C-130 (US), G-V, WB-57, ER-2, Geophysica, NASA Global Hawk, and the NASA Proteus .And here's our very own picture of a US Forest Service Twin Otter used to study smoke from prescribed and wild fires:
