skyggeroller

Skyggeroller is a term associated with a type of rare atmospheric phenomenon. This phenomenon is characterized by a distinct band of rolling darkness that appears horizontally across the sky, giving the impression of a moving, daylight-obscuring cloud. The exact mechanisms behind this phenomenon are still not fully understood.

One theory suggests that Skyggeroller may be related to the rare atmospheric conditions which contribute to the formation of Mammatus clouds. While these clouds typically have rounded, pouch-like protrusions hanging from the base, the similar atmospheric conditions could potentially give rise to the more elusive Skyggeroller.

Another theory posits that Skyggeroller is related to the peculiar interactions between atmospheric temperature and pressure gradients. The phenomenon has been observed in conjunction with unusual weather patterns, involving warm and cool air masses clashing over vast distances. The specifics of the pressure distribution in such weather systems are still a topic of research and debate.

Historical accounts of Skyggeroller vary, with observed occurrences mostly documented in the Northern Hemisphere. Notable periods of increased activity include a string of events documented over Europe and North America in the late 19th century, attributed to unusually severe weather patterns during a solar minimum period.
