Wind shear height extrapolation calculator

Calculate extrapolated wind speed with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use extrapolated wind speed to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Extrapolated wind speed (m/s)

Power-law shear Utarget=Ureference(ztarget/zreference)^α; user supplies representative α.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Power-law shear Utarget=Ureference(ztarget/zreference)^α; user supplies representative α. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
