WndSp2m: Wind Speed at the height 2 m Above Ground Surface
Description
WndSp returns the value of wind speed at the height 2 m above the ground surface.
Usage
WndSp2m(u_z, z, speed = NULL)
Value
The function returns the value of the wind speed [m/s] as a numeric scalar.
Arguments
u_z
Optional. A numeric scalar that denotes the measured wind speed at z m above ground surface [m/s].
z
A numeric scalar that denotes the height of measurement above ground surface [m].
speed
Optional. A character string that denotes the wind speed general class and can be assigned
"str" for strong winds, "mod2str" for moderate to strong winds,
"lig2mod" for light to moderate winds, and "lig" for light winds.
This is a function to calculate the wind speed [m/s]. If u_z is missing, the function estimate the
wind speed based on wind general or empirical classes.
