Abstract: A method of determining an effect of wind on a flight path of a golf ball includes predictive modeling a flow of air through a null terrain with a processing system. The null terrain includes a three-dimensional digital model of a physical terrain and a physical feature. Changes of a wind speed, a wind direction, or a combination thereof of the flow of air are calculated with the processing system based on the predictive modeling of the wind speed and the wind direction through the null terrain. An output data set of predicted wind behavior is generated based on the calculated changes of wind speed, wind direction, or a combination thereof of the flow of air through the null terrain. An effect of wind behavior on the flight-path of the golf ball is predicted based on the output data set of predicted wind behavior.
