will10b: Calculate n for the Willoughby model

In stormwindmodel: Model Tropical Cyclone Wind Speeds

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.

Details

This function is calculating the equation:

n = 0.4067 + 0.0144 vmax_gl - 0.0038 φ

where:

• n: Parameter for the Willoughby wind model

• vmax_gl: Maximum gradient-level 1-min sustained wind (m / s)

• φ: Latitude, in decimal degrees

Value

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