Air blowing off the Strait of Georgia has a temperature of 15°C and a dew point temperature of 8°C at Vancouver (sea level). This air is forced to rise over the cordillera (the roughly parallel mountain chains of western North America). Answer the following questions showing all calculations in the space provided. Assume that the surrounding air at the top of the mountains is warmer than the rising air parcel at the summit height. a) use a simple equation to determine the elevation at which condensation begins on the western slope of the mountains. Equation with Units:

a) use a simple equation to determine the elevation at which condensation begins on the western slope of the mountains.
Equation with Units:
Lifting Condensation Level:
b) What will the temperature of the air layer be as it passes over the summit of the mountains (2400m)? Again, use an equation to determine your answer.
Equation with Units:
Temperature at the Summit:
c) Use an equation to determine the temperature in Calgary. Assume that all condensed moisture fell as rain on the windward slope.
Equation with Units:
Temperature at Calgary:
d) in a hypothetical situation, if the air mass continued to descend past Calgary to sea level, what would its
temperature be there?
Equation with Units:
Temperature at hypothetical Point X at Sea Level:
