What is a squall in meteorological terms?

A squall in meteorological terms is defined as a rapid increase in wind speed that lasts for a minute or longer. This phenomenon typically occurs when there is an abrupt change in atmospheric conditions, such as the passage of a cold front or the downdraft from a thunderstorm. The increase in wind speed is often accompanied by a sudden shift in wind direction and can bring along changes in weather, including precipitation.

Understanding this definition is crucial for pilots, as squalls can lead to turbulent conditions that may impact aircraft performance and handling during flight. For example, if a pilot encounters a squall during takeoff or landing, it may affect their approach speeds and required corrections for control inputs. Being aware of the potential for squalls in the weather forecast can help pilots prepare for these sudden wind shifts and mitigate safety risks during flight operations.
