The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3223 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to 47th Street, located 23 km away (14 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at 47th Street blows from the ENE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at 47th Street.
