The Beaufort scale is a system used to measure wind speed and its effects on the sea's surface and land. Developed in the early 19th century by Sir Francis Beaufort, it ranges from 0 to 12, with each level corresponding to specific wind speeds and associated conditions. For example, a Beaufort force of 0 indicates calm winds with smooth water, while a force of 12 signifies hurricane conditions. This scale is valuable for mariners and meteorologists as it provides a standardized method to describe wind intensity and helps in maritime navigation and weather forecasting.
