The Paraglider
Olivier Laugero is an accomplished pilot and paragliding photographer whose adventures are enough to make most of us either sick with jealousy or tremble with fear. In 2009 Olivier was the first person to land a tandem on the summit of Mont Blanc, a feat he’s repeated since.
Having grown up in Saudi Arabia, returning to the US aged eight, Jody MacDonald has scarcely stopped moving since. For the past 10 years she has lived mostly at sea and, in the last five, she’s visited more than 50 countries.
Alex Ledger the MD of SkySchool met up with Babu Sunuwar just after his epic flight from Mt Kilimanjaro.
This what he had to say:
It seems that despite years of study and some serious computing power clouds are still something of a mystery to science. Which is reassuring in a way as despite spending as much time as possible floating about under them I’ve never really got my head around them either.
“We don’t understand many basic things about clouds”
One man who’s made it his mission to better understand the way clouds work is David Romps, a scientist at the Lawrence Berkeley National Laboratory scientist in the USA. “We don’t understand many basic things about clouds,” he says. “We don’t know why clouds rise at the speeds they do. We don’t know why they are the sizes they are. We lack a fundamental theory for what is a very peculiar case of fluid flow. There’s a lot of theory that remains to be done.”
Looking at the earth’s response to climate change involves the use of global climate models (GSMs) run on super-computers. However these simulations are unable to look at small scale weather systems such as clouds and Romps has had to use submodels to simulate these and observe the effect of CO2 changes in the atmosphere might have on their formation.
The image to the left shows the simulated formation of a cumulonimbus cloud in one of the submodel used by Romps.
