add_forward_speed: Adds forward speed component to modeled surface wind
In stormwindmodel: Model Tropical Cyclone Wind Speeds

Description Usage Arguments Details Value References

Adds the storm's forward speed component (i.e., motion asymmetry) back into the estimated surface wind speed at a grid point location after rotational winds have been modeled for the location.

1	add_forward_speed(wind_sfc_sym, tcspd_u, tcspd_v, swd, cdist, Rmax)

`wind_sfc_sym`	A numeric vector with maximum 10-meter 1-minute sustained wind with motion asymmetry removed (m / s).
`tcspd_u`	A numeric vector with the tropical cyclone speed, u-component (m / s).
`tcspd_v`	A numeric vector with the tropical cyclone speed, v-component (m / s).
`swd`	A numeric vector with surface wind direction (in degrees).
`cdist`	A numeric vector giving radius (in kilometers) from the storm center to the location being modeled.
`Rmax`	A numeric vector giving the radius to maximum winds (in kilometers) for the tropical storm.

This function uses equation 12 from Phadke et al. (2003).

A numeric vector giving asymmetric surface windspeed (m / s) at the location being modeled.
