2. (a) The temperature of the parcel after it has descended down the lee side of the mountain to sea level will depend on the local climate and weather conditions.
(b) The source of the heat energy is the compression of the air as it descends down the mountain. As the air is compressed, it is heated up due to the increase in pressure.
3. (a) On the windward side of the mountain, the relative humidity of the parcel is decreasing as it rises from sea level to 3000 meters.
(b) This is because as the air rises, it expands and cools, causing the relative humidity to decrease.
4. (a) On the lee side of the mountain, the relative humidity of the parcel is increasing as it descends from 6000 feet to sea level.
(b) This is because as the air descends, it is compressed and heated up, causing the relative humidity to increase.
2. (a) After the parcel of air has descended down the lee side of the
mountain to sea level, what is the temperature of the parcel?
(b) Why is the parcel now warmer than it was at sea level on the windward side (what
is the source of the heat energy)?
3. (a) On the windward side of the mountain, is the relative humidity of the parcel increasing or decreasing as it rises from sea level to 3000 meters?
(b) Why?
4. (a) 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?
b) Why?
