Calculates \(n\), a parameter for the Willoughby model, using equation 10b (Willoughby et al. 2006).
will10b(vmax_gl, tclat)
Numeric vector of the tangential wind component of the maximum gradient wind speed, in meters per second
Numeric vector of the absolute value of latitude, in degrees.
A numeric vector for \(n\), a parameter needed for the Willoughby wind model.
This function is calculating the equation: $$n = 0.4067 + 0.0144 V_{max,G} - 0.0038 \phi$$ where:
\(n\): Parameter for the Willoughby wind model
\(V_{max,G}\): Maximum gradient-level 1-min sustained wind (m / s)
\(\phi\): Latitude, in decimal degrees
