Consider two parcels of air, one in Honolulu, HI and the other in Anchorage, AK. Each contains 1 kg of dry air plus some water vapor. Assume that they are both at a pressure of about 1000 mb.
- The parcel in Honolulu has a relative humidity of 45% and a temperature of 80 degrees Fahrenheit. At that temperature, the parcel of air is capable of "holding" at most about 35 grams of water vapor.
- The parcel in Anchorage has a relative humidity of 80% and a temperature of 60 degrees Fahrenheit. At that temperature, this parcel is capable of "holding" at most 18 grams of water vapor.
QUESTIONS:
A) Which parcel has the most water vapor in it? Show your solution.
B) What would happen to the amount of water vapor in the Honolulu parcel if it were cooled to the same temperature as the air in Anchorage?
C) What would its relative humidity be then?
