Wind Shear Profile Calculator
Calculate wind speed at different heights using wind shear coefficients
About this calculator
The Wind Shear Profile Calculator determines wind speeds at various heights above ground using established wind shear coefficients and power law relationships. This tool is essential for wind energy assessments, aviation planning, meteorological studies, and structural engineering projects. By inputting reference wind speed, height, and terrain characteristics, engineers and meteorologists can accurately predict wind behavior at different elevations, enabling better design decisions for wind turbines, tall structures, and flight operations.
How to use
Enter the reference wind speed and its measurement height, then select the appropriate terrain type or input a custom wind shear coefficient. Specify the target height where you want to calculate wind speed. The calculator applies the power law formula to determine the wind speed at your desired elevation based on atmospheric boundary layer principles.
Frequently asked questions
What is wind shear coefficient?
Wind shear coefficient (alpha) represents how wind speed changes with height. It varies by terrain type, from 0.1 over water to 0.4 in cities.
What heights can I calculate wind speeds for?
You can calculate wind speeds for any height above ground, typically from 2 meters to several hundred meters, depending on your application needs.
How accurate are wind shear calculations?
Wind shear calculations provide good estimates under neutral atmospheric conditions but may vary with weather, temperature gradients, and local terrain features.
