Cloud suck The telltale signs for a pilot climbing in the thermal under a "sucking" cloud are (1) lift strengthening, (2) lift getting smoother, and (3) widening of the thermal. Paraglider pilots have reported being unable to descend in strong cloud suck, even after bringing their canopies into deep spiral, which would normally result in a rapid vertical descent. Cloud suck is especially dangerous for paraglider pilots, whose maximum speed is less than 30 knots, because storm clouds (Cumulonimbus) can expand and develop rapidly over a large area with accompanying large areas of strong lift.

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.
