PART A: Questions 1-5 refer to the diagram below.. WEST EAST 3000 feet - Mountain 1000 feetV At V, the temperature is 81°F and the Dewpoint T 75.5°F. If you need to use the WALR, then assume a WALR of-3.5°F/1000ft. 1. Location V is on the windward side or leeward side (circle one) of the mountain. The specific humidity at location V is higher or lower (circle one) than at location X. 2. As an air mass moves from the bottom of this mountain to the top.... it will expand or compress (circle one) the air temperature will increase or decrease (circle one) ...the relative humidity will increase or decrease (circle one) 3. At location V M C R X (circle all that are correct), the relative humidity is 100%. 4. The air temperature at location X is . The dewpoint temperature at location X is This diagram, illustrating that air is sometimes forced to flow up and over topographic barriers, is an example of the 5. Condensation is occurring between what two locations (circle two)? V M CRXExplanation / Answer
1. Location V is on the Leeward side of the mountain.
The Specific Humidity at Location V is lower than that at X.
2. As an air mass moves from the bottom of this mountain to the top,
- It will expand.
- The air temperature will decrease.
- The relative humidty will dcecrease.
3. At Location X , the relative humidity is 100%.
4. At X, the realtive humidity is 100%. So, temperature and dewpoint at this location are the same.
Since temperature at V is 81 degree F, so temperature at X is also 81 degree F since these two locations are located in the same latitude. Temperature at two different places across the same latitude are same. Consequently, the dewpoint at X is also 81 degree F since the relative humidity here is 100%.
This diagram, illustrating that air is sometimes forced to flow up and over topographic barriers, is an example of 'Orographic Lift'.
5. Condensation is occurring between the latitudes C and R.
