BEAUFORT NOTATION Meaning and
Definition
-
Beaufort notation refers to a system of numerical and descriptive scales used to quantify and communicate wind speed and its associated impacts on land and sea conditions. The notation is named after Sir Francis Beaufort, a British naval officer, who introduced it in the early 19th century.
The Beaufort notation typically ranges from 0 to 12, with each number representing a different wind force. The scale starts with 0, indicating a calm or light breeze with wind speeds below 1 mph. As the numbers progress, the wind force and its effects become more significant. For example, a Beaufort number of 8 corresponds to a fresh gale with sustained wind speeds between 39 and 46 mph, resulting in significant damage to trees and buildings.
Alongside numbers, the Beaufort scale includes descriptive terms to further clarify the observed conditions. These terms, ranging from "calm" and "light air" to "hurricane," provide additional details about the wind's behavior, such as whirls, lift-offs, and wave heights.
The Beaufort notation is widely used in meteorological reports, maritime charts, and aviation weather observations, enabling consistent and standardized communication of wind conditions across different regions and platforms. By utilizing this scale, meteorologists, sailors, and pilots can quickly understand and convey the potential hazards and safety measures associated with varying wind speeds.
Etymology of BEAUFORT NOTATION
The word "Beaufort notation" refers to a scale for measuring wind speed, known as the Beaufort scale. The term "Beaufort" in Beaufort notation comes from Sir Francis Beaufort, an Irish Royal Navy officer, who devised this scale in the early 19th century. Beaufort developed the scale to standardize and describe the effects of wind on a ship's sails and its ability to navigate. It later became popular for general use, including meteorological purposes.
