Wind Shear Profile Calculator
Calculate wind speeds at different heights using power law and logarithmic wind shear models
About this calculator
The Wind Shear Profile Calculator determines wind speeds at various heights above ground using established atmospheric models. This tool applies power law and logarithmic wind shear equations to predict how wind velocity changes with elevation, essential for wind energy assessment, aviation safety planning, and meteorological analysis. Engineers, pilots, and renewable energy professionals rely on these calculations to optimize turbine placement, assess flight conditions, and understand atmospheric boundary layer behavior for project planning and risk assessment.
How to use
Enter the reference wind speed and height where it was measured, then specify your target height for calculation. Select either the power law or logarithmic model based on your terrain and application needs. The calculator will instantly compute the predicted wind speed at your desired elevation using the chosen atmospheric model.
Frequently asked questions
What's the difference between power law and logarithmic models?
Power law is simpler and works well for open terrain, while logarithmic model accounts for surface roughness and is more accurate for complex terrains.
What height range is suitable for these calculations?
These models work best between 10-200 meters height. Beyond this range, other atmospheric factors significantly influence wind patterns and accuracy decreases.
Which model should I use for wind turbine site assessment?
Use logarithmic model for detailed assessments as it considers terrain roughness. Power law works for preliminary estimates in relatively uniform terrain conditions.
