Consider a parcel of air arriving at the Posts coast with a temperature of 150°C and a dewpoint temperature of 100°C. Since the winds here generally move from west to east, it can be expected to pass over the Santa Lucias and drop down to Welby. Keep in mind what is happening in terms of adiabatic processes, and assume that any water that condenses will fall out of the air as rain.

Required:
a. At what elevation will condensation begin?
b. What will the temperature be at the crest of the mountains and points shown on the mountains?
c. What will the relative humidity of the air be at the crest of the mountains?
d. What will the dewpoint temperature be at the crest of the mountains?
e. What will the temperature of the air be at Welby?
f. What will the dewpoint temperature be at Welby?
g. How has the temperature and actual humidity of the air changed between Posts and Welby?
h. How would you expect the combination of prevailing wind direction and adiabatic processes to affect the climates of Posts and Welby?
