eh <br />ESPEY, HUSTON BASSOCIATES, INC. <br /> <br />3.0 RESULTS AND DISCUSSION <br />3.1 ANEMOMETER MEASUREMENTS <br />The data collected at the north and south anemometers indicate the <br />complexity of the winds at the mine site. Figure H-3 is a wind rose for the north <br />met station, and Fig. H-4 is a wind rose for the south station. <br />It appeazs that the flow at the mine site is almost totally controlled by <br />the local topography. While a diurnal up/down canyon flow is observed on many <br />days, it is not always present. The Curtis Creek Canyon probably has a venturi <br />effect on the wind speeds. The venturi effect may cause the wind to increase in <br />speed through the aazrow part of the canyon and then slow down upon exiting the <br />nazrow pazt. The south wind rose also shows the influence of the White River <br />• airshed. The comparison of the two also shows that, for a significant amount of the <br />time, the winds aze flowing through Curtis Creek Canyon. <br />3.2 TEMPERATURE <br />The maximum, minimum and average temperatures for each month in <br />1979 aze presented in Table H-1. The data presented are from the Meeker reporting <br />station. The data collected at the north and south meteorological stations indicate <br />that the temperature at the mine site is usually lower than the temperature at <br />Meeker by 5-10° F. This is probably caused by the steep terrain at the mine site. <br />At Meeker, the maximum temperature recorded was 96o F in August of 1979, and <br />the minimum temperature recorded was -27° F in both November and December of <br />1979. <br />C~ <br />H-9 <br /> <br />
