This is a supercell cumulonimbus cloud suitable for use with real-world weather and preset weather themes.
To install, simply unzip and copy the file "supercell.cld" into: Flight Simulator 9\Weather\clouds
To enable the supercell to be seen on Flight Simulator, copy and paste the following into your CloudArtFiles.xml, inserting it into the relevant cumulonimbus sections. Back up the original CloudArtFiles first.
NB: the CloudArtFiles.xml prefers to open in Internet Explorer, so right click on its icon and open it with notepad to edit it.
CAUTION: This cloud file is very large and will slow down your frame-rates. Don't use if you have a slow computer or it will protest. That said, it's good eye-candy
