The term "circulating light" encompasses a set of objects with anomalous properties in which circulating light is the cause of these anomalies. Such objects include natural ball lightning, luminous objects arising from attempts to obtain artificial ball lightning in the laboratory, as well as objects responsible for the phenomenon of sonoluminescence and cavitation. We represent natural ball lightning in the form of ordinary white light, which circulates in all possible directions in the shell in the form of a thin spherical layer of highly compressed air, which is compressed by the same light. The density of light energy in such an object is extremely high. As a result, it is subject to the action of optically induced forces. The magnitude of these forces is negligible at ordinary light intensity but increases by billion times at an interaction with the circulating light. Using the well-known laws of optics and physics and taking into account the action of these forces, all the features of the behavior of ball lightning, which were reported by eyewitnesses, were explained. Now we explain the behavior of the circulating light in situations that is not acceptable for direct observation. These are the properties of large ball lightning, the behavior of ball lightning inside a tornado, and its behavior in pipelines through which gases are pumped.
