wind_speed_profile_neutral {TrenchR}

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 Sellers (1965). Function is equations (2) and (3) of Porter et al. (1973).

Usage

wind_speed_profile_neutral(u_r, zr, z0, z)

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).

Value

numeric windspeed (m s^-1).
