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 number corresponding to specific wind speeds and effects. For example, a Beaufort Scale of 0 indicates calm conditions, while a scale of 12 represents a hurricane. This scale helps sailors, meteorologists, and outdoor enthusiasts understand wind conditions and their potential impact. By observing the movement of trees, waves, and other indicators, users can determine the appropriate Beaufort number and make informed decisions regarding safety and activities.
