stormwindmodel (version 0.1.4)

will10b: Calculate n for the Willoughby model

Description

Calculates \(n\), a parameter for the Willoughby model, using equation 10b (Willoughby et al. 2006).

Usage

will10b(vmax_gl, tclat)

Arguments

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.

Value

A numeric vector for \(n\), a parameter needed for the Willoughby wind model.

Details

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
