1. What is Wind Speed at Elevation 10m?

Wind Speed at Height of 10 m refers to the average speed of the wind measured at a height of 10 meters above ground level. This measurement is crucial for various meteorological and oceanographic studies.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{10} \) — Wind Speed at Height of 10 m (m/s)
• \( F_l \) — Fetch Length (m)
• \( g \) — Gravitational acceleration (9.80665 m/s²)
• \( \alpha \) — Dimensionless Scaling Parameter

Explanation: This formula calculates wind speed at 10m elevation based on fetch length and dimensionless scaling parameter, which is used in the JONSWAP spectrum for fetch-limited seas.

3. Importance of Wind Speed Calculation

Details: Accurate wind speed estimation at standard height is crucial for weather forecasting, marine operations, wind energy assessment, and environmental studies.

4. Using the Calculator

Tips: Enter fetch length in meters and dimensionless scaling parameter. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is fetch length?
A: Fetch Length is the unobstructed distance that wind can travel over water in a constant direction.

Q2: What is dimensionless scaling parameter?
A: Dimensionless Scaling Parameter is a value used in mathematical or scientific models to scale or normalize variables without units.

Q3: Why is 10m height standard for wind measurement?
A: 10m height is internationally standardized for meteorological measurements to ensure consistency and comparability across different locations.

Q4: What are typical wind speed values at 10m height?
A: Typical values range from 0-25 m/s, with calm conditions around 0-2 m/s and storm conditions exceeding 20 m/s.

Q5: How accurate is this calculation method?
A: This method provides good estimates for fetch-limited seas but may have limitations in complex terrain or rapidly changing weather conditions.
