What is a pressure flip?

A pressure flip refers to a sudden change in pressure conditions that causes a rapid shift in a system's state, often seen in fluid dynamics or meteorology. For instance, in weather systems, a pressure flip can occur when high-pressure air masses displace low-pressure systems, leading to dramatic changes in weather patterns. This phenomenon can also apply to engineering contexts, such as in pressure vessels or pipelines, where a rapid change in internal pressure can lead to structural failure or other critical events.
