As you are aware the upper reathe watershed typically experiences westerly surface winds based on mid-lattade atmospheric circulation features. figure 2 shows the watershed digital elevation model (dem. the elevation along the indicated cost and the p a gwesterly wind direction figure 2. (lett panel): dem of the upper feather watershed showing a west-to-cast cross-section location and the prevailing wind direction (right panel): elevational cross-section along line shown in left panel and the cka hase level this problem involves orographically driven processes that result from air parcels that enter the watershed at the cross-section shown above at point a and follow the topographic cross section from west to east. the prevailing wind brings air into the watershed at point alatan elevation of 1820 m, where this elevation corresponds to a pressure level of 81800 pa. the onographic uplift-driven cloud base is observed to occur at an elevation of 2200 m, where this elevation corresponds to a pressure level of 7000 pa. the temperature of an air parcel at the cloud base is 17°c. based on this information, answer the following a) what is the specific humidity of the air at the cloud base? b) considering only the orographic uplift process, what is the expected temperature of near-surface a that comes into the watershed at point a? c) what is the expected relative humidity of the air at point a? d) qualitatively, how would the cloud base level change if the temperature of air parcels entering the watershed were colder (with all else equal? justify your answer. e qualitatively, how would the cloud base level change if the air parcels entering the watershed had a lower specific humidity (with all else equal justify your answer suppose at the c hase the cloud droplets are characted by a marshall-palmer drops distribution where the average drop diameter is 0.5 mm for simplicity assume the terminal velocity of a droplet is proposal to its date with a propostat constant of 2500 s f the updatt velocity were what dresses diameter in mic ) would contribute to precio leaving the ckad buses. those that would mod write down the appropriate expression for the preciation leaving the c hose in this case in the simpler case where the updraftvelocity is negligibly small. compute the predicted precipitation teaving the c hosenho
