ATOC 1050 RECITATION QUESTIONS
WITH CORRECT ANSWERS
You wake up in the morning and observe dew on the grass outside. The dewpoint
temperature remained the same from the previous evening to the morning and the
atmosphere was not saturated the night before. How did the atmosphere get to
saturation by the morning? - ANSWER-The air temperature decreased overnight.
What term describes the lowest temperature to which air can be cooled at constant
pressure before saturation occurs? - ANSWER-dewpoint temperature
At night, as the air temperature falls, what typically happens to the relative humidity? -
ANSWER-It increases.
Which of the following will not increase the relative humidity (RH) of air? - ANSWER-
increasing the air temperature (and holding the dewpoint temperature constant).
True or false The relative humidity can be decreased by either adding moisture to an air
parcel or by cooling that air parcel. - ANSWER-False
True or False The higher the value of the dew point temperature, the lower the actual
vapor pressure. - ANSWER-False
True statements about latent heat: - ANSWER-Latent heat warms the atmosphere
during condensation. Latent heat is the energy required to convert liquid water to vapor.
During the process of evaporation latent heat is__ the atmosphere, resulting in a ___ air
temperature. - ANSWER-consumed by; cooler
I have a closed jar ½ filled with water. It has been left alone for a few days and the air in
the jar is now saturated. What will happen if I start to increase the temperature of the jar
(thus the air and water inside)? - ANSWER-More liquid water will start to evaporate
because the air is no longer saturated.
True or False The primary method by which upper air weather observations are
collected is drone aircraft. - ANSWER-False
True or False If the actual vapor pressure and saturation vapor pressure are similar in
value, then the relative humidity is very high (i.e., close to 100%) - ANSWER-True
True or False A sea level pressure reported on a surface station model as 242 would
actually be 924.2 mb. - ANSWER-False
