Wind Speed Calculator UK

Wind Speed Formula:

\[ v = \text{measured wind speed} \]

Adjusted Wind Speed (m/s):

Definition: This calculator adjusts wind speed measurements based on height and terrain factors according to UK standards.

Purpose: It helps engineers, architects, and meteorologists account for wind speed variations at different heights and terrain types.

The calculator uses the formula:

\[ v = \text{measured wind speed} \times \left(\frac{h}{10}\right)^\alpha \]

Where:

Explanation: The formula adjusts the measured wind speed to account for height variations and terrain roughness.

Details: Accurate wind speed calculations are crucial for structural design, wind load assessments, and renewable energy projects.

Tips: Enter the measured wind speed in m/s, measurement height (default 10m), and terrain factor (default 0.16). All values must be > 0.

Q1: What is the standard reference height?
A: In the UK, 10 meters is the standard reference height for wind speed measurements.

Q2: How do I determine the terrain factor?
A: Use 0.16 for open terrain, 0.28 for urban areas, and 0.40 for city centers with tall buildings.

Q3: Why adjust wind speed for height?
A: Wind speed increases with height due to reduced surface friction (wind gradient effect).

Q4: Is this calculator specific to UK standards?
A: Yes, it follows UK building regulations and wind loading standards (BS EN 1991-1-4).

Q5: Can I use this for wind turbine calculations?
A: Yes, but consult specific wind turbine guidelines for additional factors to consider.
