Beaufortskála

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. It was created by Sir Francis Beaufort in 1805 and has been used ever since as an empirical measure to describe wind conditions. The scale assigns numbers to specific wind speeds and describes the resulting conditions and their effects on the environment. The scale is divided into 13 levels, ranging from 0 (calm) to 12 (hurricane). Each level is associated with a specific range of wind speeds and a description of the conditions that can be expected. The scale is widely used in meteorology, aviation, and maritime operations to communicate wind conditions and their potential impacts. The Beaufort scale is based on visual observations of the sea and land, and it does not provide precise wind speed measurements. However, it is a useful tool for estimating wind speeds and understanding the effects of wind on the environment. The scale has been updated over the years to reflect changes in technology and our understanding of wind conditions. Despite its limitations, the Beaufort scale remains an important tool for communicating wind conditions and their potential impacts.
