UADJ

The wind function which was found to give the best results can be used to obtain an initial estimate of UADJ.
The initial estimate of UADJ would be 0.002 multiplied by the average wind movement in kilometers for 6 hours at a height of one meter above the snow surface during a rain-on-snow event.
Lower values of UADJ are commonly associated with heavily forested watersheds, while the higher values usually occur in generally open areas.
However, there are many exceptions, thus it is best to base the initial estimate of UADJ on a knowledge of typical wind speeds during rain-on-snow events at the particular location being modeled.
