7000 frames per second Newscientist article, with links to the movies. "Atmospheric 'sprites' captured in explosive detail ... by researchers using an ultra-high-speed camera. "The best images yet of the flashes – which resemble a giant undulating jellyfish with its tentacles falling from a halo of light – have allowed the team to pick apart their structure and mechanics.

"We pledge to fight ‘blue-sky thinking’ wheresoever we find it!"
Clouds can be strange looking, majestic, colourful, freaky, ominous or electric to name but a few.
Perhaps you’d like to go cloud ’surfing’ in a glider along a 600 mile cloud formation that appears in Queensland (film links/explanation) later in the year?
Or would you rather view your clouds from satellite?
You can otherwise study cloud formations at your leisure if you want.

There’s a million more sites around of course – first link via.

Enviromental absorbant products manufacturer, Dyn-O-Mat claims to have removed a cloud from Doppler radar and intends to test their product on a hurricane. They have a patent and everything. The federal government spent two decades on Project Stormfury, an attempt to halt storms by 'seeding' the eyewall of a hurricane. This guy says we are already doing it with the militaries High Frequency Active Auroral Research Program. Even if we're not doing it now, we'll definately by own the weather by 2025. That is, unless we're intentionally causing storms.

Clouds formed at sea may be created by plankton to protect themselves from harsh UV rays by inducing more dimethyl sulfide to the atmosphere.
