The Beaufort scale is a system used to estimate wind speed based on observed conditions at sea or on land. Developed by Sir Francis Beaufort in 1805, it ranges from 0 to 12, with each level corresponding to specific wind speeds and effects. For example, a Beaufort scale of 0 indicates calm winds, while a level of 12 signifies a hurricane. This scale helps sailors, meteorologists, and outdoor enthusiasts understand wind conditions. It is particularly useful for predicting weather patterns and assessing the impact of wind on various activities, such as sailing or construction.
