Direction is in degrees from north as measured by a compass.
The number entered for Wind Variability is used to create a wind speed in a range plus or minus this amount. The model selects a uniformly distributed value from this range for the value of wind speed. If you use wind variability, please be aware that you answered will change with each evaluation even though you don't change the data. This is because wind speed used in the model is a true random variable. The table allows for wind to change direction on different parts of the course.
