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.
add_forward_speed(wind_sfc_sym, tcspd_u, tcspd_v, swd, cdist, Rmax)A numeric vector with maximum 10-meter 1-minute sustained wind with motion asymmetry removed (m / s).
A numeric vector with the tropical cyclone speed, u-component (m / s).
A numeric vector with the tropical cyclone speed, v-component (m / s).
A numeric vector with surface wind direction (in degrees).
A numeric vector giving radius (in kilometers) from the storm center to the location being modeled.
A numeric vector giving the radius to maximum winds (in kilometers) for the tropical storm.
A numeric vector giving asymmetric surface windspeed (m / s) at the location being modeled.
This function uses equation 12 from Phadke et al. (2003).
