View source: R/willoughby2006eqs.R

Description

Calculates X1, a parameter for the Willoughby wind model using equation 10a (Willoughby et al. 2006).

Usage

1
will10a(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 uses the following equation (equation 10a, Willoughby et al. 2006) to calculate the X1 parameter:

X1 = 317.1 - 2.026vmax_gl + 1.915 φ

where:

Value

A numeric vector giving one of the parameters (X1) required for the Willoughby wind model.
