What is Closed Row (Cut Off Low)?

A closed low, also known as a cut-off low, is a low-pressure system that is entirely isolated from the main atmospheric circulation patterns. These systems are surrounded by high-pressure areas and can result in persistent weather conditions such as heavy rain, thunderstorms, or cold temperatures in a localized area.
