Question
2. Air Temperature and Dewpoint temperature for three locations are listed below. Remember that air temperature is closely related to the holding capacity of the air and dewpoint temperature is most closely related to the actual amount of water vapor in the air Air Temp Dewpoint Temp City A City B City C City D City E SSF 82°F 75°F 79°F 75°F 40°F 69°F 71°F 73°F 45°F a. Which city has the largest relative humidity? b. Which City has the lowest relative humidity? c. Which city has the greatest amount of water vapor in the air? d. Which city has the least amount of water vapor in the air?Explanation / Answer
a. Relative Humidity (RH) is a function of how close the temp is to the dew point temp. The closer these are together, the higher the RH. The further they are a part, the lower the relative humidity. To find the highest RH we look for the city with the smallest difference between the temp and the dew point temp. Thus City C
b. To find the lowest RH we look for the city with the largest difference between the temp and the dew point temp. Thus city E
c. Dew point temperature shows the water vapor content of the air. The city with the highest dew point temperature is the one with the highest amount of water vapor in the air. thus city D
d.The city with the least dew point temperature is the one with the least amount of water vapor in the air. thus city A
