5.2.9 Two Rivers Data Summary
Two Rivers was one of the more calm sites in the network with maximum recorded wind
speeds of only 11.45 m/s. This site had a very low frequency of wind speeds above 8 m/s,
which is what could be expected from a site that is fairly sheltered inside a river valley.
The wind most typically blew from the northeast, which was to be expected, as that is the
along-valley direction for the New Fork River Valley; however, wind very seldomly blew
from the southwest, which is the other along-valley direction that the wind could blow.
This could be due to the intersection of the Green River Valley with the New Fork River
Valley just to the southwest of the site location. A secondary wind direction frequency
maximum is from the northwest, which is the direction of the Green River Valley from
the site location. The wind direction with the lowest frequency of occurrences was the
southeast quadrant, which is the direction of Ross Butte from the site location.
Diurnally, wind speeds were generally very low throughout the night, with a maximum in
the mid-afternoon. The morning wind shift occurs between 9:00 and 13:00 and changes
the wind direction from NNW to WNW. There is a secondary wind shift that occurs
between 16:00 and 21:00, which changes the wind direction from WNW back to NNW.
