answers from exercise 9:

Step #1:

1:    should look similar to figure 7-2, p. 182 of text

2:    2.2mb, 30.1mb.

3:    23.4mb, 53%

4:    dewpoint is 10 degrees celsius, must cool 10 degrees celsius...

5:    22%

6:    12.7mb

7:    this is because as air gets warmer its capacity to hold water also increases.   Even though the air over the Sahara has more water, however, it still usually has a lower relative humidity (it is a desert, remember) than temperate latitudes.
 

Step #2:

1:    you should have read this over, but since we didn't actually use the psychrometer in class, there's no answer required.

2:

dry-bulb temperature
wet-bulb temperature
wet-bulb depression (c)

Step 3:

no answers required, but remember to know what albedo is!

Step 4:

ditto: know about environmental lapse rate and adiabatic rates!

Step 5:

we'll return to this topic later; not required this week

Step 6:

1:    12 degrees c - despite the workbook's prompting, there's no "work" required to get the answer other than using the figure 9.1 you filled in on p. 146.

2:    900m/2953'

3:    MAR

4:    3 degrees c

5:    21.1 degrees c

6:    at 600m on windward side the air could be cooler by 15 degrees.   Latent heat released during condensation on windward side was greater than that used for evaporation on leeward side.

7:    this should note something about how the leeward side would be warmer and drier than the windward side.   Rain shadow is a good term to use here...

8:    Look these up in your text, and think about their location relative to mountains (...duh)

Step 7:

you didn't need to do...
