Nimbostratus cloud to a surface observer. Nimbostratus usually has a thickness of about 2000 to 4000 m. Though found worldwide, nimbostratus occurs more commonly in the middle latitudes. It is coded C2 on the SYNOP report. Nimbostratus occurs along a warm front or occluded front where the slowly rising warm air mass creates nimbostratus along with shallower stratus clouds producing less rain, these clouds being preceded by higher-level clouds such as cirrostratus and altostratus. Often, when an altostratus cloud thickens and descends into lower altitudes, it will become nimbostratus. Nimbostratus, unlike cumulonimbus, is not associated with thunderstorms, however at an unusually unstable
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.
