Cloud If the air becomes more unstable, the cloud tends to grow vertically into the species "mediocris", then "congestus", the tallest cumulus species which is the same type that the International Civil Aviation Organization refers to as 'towering cumulus'. With highly unstable atmospheric conditions, large cumulus may continue to grow into cumulonimbus "calvus" (essentially a very tall congestus cloud that produces thunder), then ultimately into the species "capillatus" when supercooled water droplets at the top of the cloud turn into ice crystals giving it a cirriform appearance. All cloud varieties fall into one of two main groups. One group identifies the
Cloud swing stationary rig, with the swing itself hanging in a "V" shape. Generally, the motion provided to swing the performer is supplied by an assistant pulling on a tether at the bottom of the "V". "Cloud swing" is often performed at lower altitudes relative to "Mexican cloud swing". This is what distinguished "cloud swing" from "Mexican cloud swing". The cloud swing is a relatively new apparatus, and many of the figures performed on it are borrowed or adapted from static and swinging trapeze.
