remove_forward_speed: Remove forward speed from maximum wind speed

Description Usage Arguments Details Value References

View source: R/wind_conversions.R

Description

Removes the forward speed of the storm from the maximum storm wind speed, Vmax, to estimate Vmax,sym, the storm's maximum 10-m 1-min sustained wind with motion asymmetry removed.

Usage

1
remove_forward_speed(vmax, tcspd)

Arguments

vmax

A numeric vector giving maximum 10-m 1-minute sustained wind (m / s)

tcspd

A numeric vector giving the tropical cyclone's forward speed (m / s).

Details

This function is based on equation 12 (and accompanying text) in Phadke et al. 2003. Based on this paper, the correction factor for forward speed is at its highest at the radius of maximum winds, where it equals 0.5 times the forward wind speed.

Value

A numerical vector with Vmax,sym, the storm's maximum 10-m 1-min sustained wind with motion asymmetry removed, in m / s.
