<br />The fonner have large flux values per hour but are relatively rare. The latter are so numerous that <br />summation of their limited flux per hour is significant over the course of a winter. <br /> <br />o <br />O'l <br /> <br />* <br /> <br />o <br />CXJ <br /> <br />o <br />" <br /> <br /> <br />MOGOLLON RIM <br />Y = -0.292 + 0.175 X <br />R = 0.88 <br />N = 11 <br /> <br />......... <br />Eo <br />EtD <br />......... <br /> <br />go <br />:.;::1/') <br />c <br />:!:: <br />.e-o <br />O""l;f" <br />Q) <br />~ <br />a. <br />o <br />c~ <br />...- <br />o <br />I- <br />o <br />N <br /> <br />* <br /> <br />* <br /> <br />o <br /> <br />~ <br /> <br />200 . 300 400 <br />Total SLW Flux (Mg/m) <br /> <br />Figure 3-2. - Storm total SLW flux vs. total precipitation based on 1987 data from the Mogollon Rim. <br /> <br />It is of interest to compare the total SL W flux each season with the runoff from the Beaver River, which <br />drains the west side of the 50 kIn north-south Tushar Mountain Range. Long (1986) gives a. figure of <br />38,250 acre-ft for the mean annual runoff of the Beaver River, Column 3 of table 3.2 gives the total <br />estimated flux per season from table 3.1, but in units of acre-feet for the 50 kIn north-south extent of the <br />Tushars. The approximate duration of available radiometer observations, also extracted from table 3.1, <br />is given in column 2. Assuming the 1.0 to 1.5 months of available data was representative of each entire <br />winter allows estimates to be made of the total flux for 5.0-month winters (column 4). These estimates <br />are admittedly crude but should yield a first approximation of excess SL W flux over the mountain range. <br />It should be remembered that some unknown portion of the flux over the radiometer, located 5 kIn upwind <br />from the ridgeline, will be naturally converted to snowfall before reaching the lee subsidence/evaporation <br />zone. Thus, the estimates of column 4 are somewhat optimistic. <br /> <br />Column 5 shows the estimated 5-month flux as a percentage of the mean annual runoff of the Beaver <br />River. (If one wishes to compare the 5-month flux values to the entire runoff from both sides of the <br />Tushar Mountains, the values of column 5 should roughly be halved), It is seen that the 5-month flux <br />estimates are about 1.9 to 3~7 times the runoff from the west side of the Tushar Mountains. A similar <br />estimate was made for the west side of the lower, more gentle Mogollon Rim of northern Arizona which <br /> <br />16 <br />
