Definition
- Noun:
- A scale from 0 to 12 for the force of the wind: The Beaufort scale is a standardized system for estimating and reporting wind speed based on observed sea or land conditions, rather than precise instrument measurements.
- An international scale of wind force from 0 (calm air) to 12 (hurricane): It is an internationally recognized empirical measure that correlates specific ranges of wind speed (e.g., in knots or miles per hour) with descriptive terms and observable effects.
Usage Examples
- Noun:
- According to the Beaufort scale, winds of force 8 are classified as a gale.
- The meteorologist estimated the wind speed by observing the wave patterns and consulting the Beaufort scale.
- Force 0 on the Beaufort scale indicates calm conditions with smoke rising vertically.
Advanced Usage
- "To estimate/measure something on the Beaufort scale": To assess wind force using this specific system.
- Sailors are trained to estimate wind speed on the Beaufort scale by looking at the sea state.
- The scale is often used descriptively in weather reports and maritime forecasts.
- The forecast warns of winds increasing to Beaufort force 6 (strong breeze) by this evening.
Variants and Related Words
- Wind force (n): The strength or power of the wind, which the Beaufort scale measures.
- Wind scale (n): A general term for any system that categorizes wind speed; the Beaufort scale is the most common example.
Synonyms
- Wind force scale: A more generic term for the same concept.
- Wind speed scale: Emphasizes the measurement of wind velocity.
