TrenchR (version 1.1.1)

wind_speed_profile_neutral: Wind Speed at a Specific Height Under Neutral Conditions

Description

The function calculates wind speed (m s^-1) at a specified height (m) within a boundary layer near the surface. The profile assumes neutral conditions. The velocity profile is the neutral profile described by Sellers1965;textualTrenchR. Function is equations (2) and (3) of Porter1973;textualTrenchR.

Usage

wind_speed_profile_neutral(u_r, zr, z0, z)

Value

numeric windspeed (m s^-1).

Arguments

u_r

numeric wind velocity (m s^-1) at reference height.

zr

numeric initial reference height (m).

z0

numeric surface roughness (m).

z

numeric height to scale (m).
