This calculator determines wind velocity based on wave height using the empirical formula Vw = 7 + 2 × ha, where wave heights are between 1 and 7 feet. This relationship helps estimate wind speed from observed wave characteristics.
The calculator uses the formula:
Where:
Explanation: This empirical formula provides a linear relationship between wave height and wind velocity, specifically valid for wave heights between 1 and 7 feet.
Details: Estimating wind velocity from wave height is important for maritime operations, coastal engineering, and weather forecasting. It provides a practical method to assess wind conditions when direct measurements are unavailable.
Tips: Enter wave height in feet (must be between 1 and 7 feet). The calculator will compute the corresponding wind velocity in meters per second.
Q1: Why is this formula limited to 1-7 feet wave heights?
A: This empirical relationship was derived from observational data within this range and may not be accurate outside these limits.
Q2: What are typical wind velocities for different wave heights?
A: According to this formula: 1-foot waves correspond to 9 m/s wind, 4-foot waves to 15 m/s wind, and 7-foot waves to 21 m/s wind.
Q3: How accurate is this estimation method?
A: This provides a rough estimate. Actual wind velocity can vary based on fetch, duration, and other environmental factors.
Q4: Can this be used for storm forecasting?
A: While useful for general estimation, professional meteorological tools should be used for serious storm forecasting and warnings.
Q5: What units are used in this calculation?
A: Wave height is in feet while wind velocity result is in meters per second, following standard measurement conventions.
