Description

Calculates A, a paramter for the Willoughby wind model, using equation 10c (Willoughby et al. 2006).

Usage

1
will10c(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 calculates A using equation 10c (Willoughby et al. 2006):

A = 0.0696 + 0.0049 vmax_gl - 0.0064 φ

where:

Any negative values of A are reset to 0.

Value

A numeric vector that is a parameter required for the Willoughby model.
