On the lee side of the mountain, is the relative humidity of the parcel increasing or decreasing as it descends from 6000 feet to sea level? Why?
Assume that a parcel of air is forced to rise up and over a 6000-foot-high mountain (as shown). The initial temperature of the parcel at sea level is 76.5°F, and the lifting condensation level (LCL) of the parcel is 3000 feet. The DAR is 5.5°F>1000 feet and the SAR is 3.3°F>1000 feet. Assume that condensation begins at 100% relative humidity and that no evaporation takes place as the parcel descends. Indicate calculated temperatures to 1 decimal place.
