30 above conditions, these motions must bE: in the form of buoyant eddies. The 0000 analysis shows a return toward stable flow with a couple of closed off isentropes over Camp Hale as the remnants of the 2100 unsta- ble layer. Summarizing, trajectories through 1800 show smoot~1 orographic flow while those at 2100 show a distinct mixing layer dying out by 0000. 4.2 The Water Budget ;, The application of equation (5) to compute the water budget has been described. This equation was evaluated for all Be channels at six times and for the following special intervals: Minturn to Camp Hale, Camp Hale to Fairplay, TOP to Fairplay and Minturn to Fairplay. Elimination of the downslope evaporation (TOP to Fairplay) from the Camp Hale to Fairplay intervals results in the synthetic interval Camp Hale to TOP. Condensation for this interval plus the condensation for the Minturn to Camp Hale length gives the total net condensation. The results of equa- tion (5) for Minturn to Fairplay give precipitation. Figure 13 shows graphically the results of these computations. In Figure l3a the difference between the CRA-FPY curve and the CRA-TOP curve is the downslope evaporation (TOP to Fairplay), The solid and the dotted curves in l3a are summed to give the solid curve in l3b or the total con- densation. The precipitation is the dotted line in Figure l3b. With the exception of 0900, the results are in very good qualitative agreement with the surface observations discussed in section 2.2. In that section it was pointed out that light precipitation started by 1200, stopping briefly, shortly after 1800 and very light and variable snow fell from about 2100 to roughly 2300. The 0900 analysis is not valid be- cause the wind direction existing at the time does not satisfy the
