Calculates A, a parameter for the Willoughby wind model, using equation 10c (Willoughby et al. 2006).
1 | will10c(vmax_gl, tclat)
|
vmax_gl |
Numeric vector of the tangential wind component of the maximum gradient wind speed, in meters per second |
tclat |
Numeric vector of the absolute value of latitude, in degrees. |
This function calculates A using equation 10c (Willoughby et al. 2006):
A = 0.0696 + 0.0049 vmax_gl - 0.0064 φ
where:
A: Parameter for the Willoughby wind model (any value of A calculated as negative is re-set to 0)
vmax_gl: Tangential component of the maximum gradient-level sustained wind speed (in m / s)
φ: Latitude, in decimal degrees
Any negative values of A are reset to 0.
A numeric vector that is a parameter required for the Willoughby model.
