Polar diagram showing modeled airspeed averaged across the sexes as a function of wind speed and relative wind direction for six different wind speeds as calculated with a linear model (Eq. 4). The average wind speed is 9.0Â m/s so the airspeed curve for this wind speed (light blue) is representative of average airspeeds. Across-wind components of modeled air velocity are plotted against upwind components of modeled air velocity
