Problem 1: Pretend a classroom has 35 students sitting quietly in it. It has a certain amount of actual water vapor in it (specific humidity). The doors and windows are closed. Continue to pretend that the heat in the room has risen by 10oF and the room is much warmer. The amount of actual water vapor has not changed. What has happened to the relative humidity (RH) of the air in that room of students in the warmer air? (ignore students sweating) Has the RH increased or has the RH decreased? Describe why you answered the way you did.
Problem 2: With all that in mind, imagine two dew point temperatures: 11oF and 74oF. Which one might represent a summer day in Las Vegas, and which one might represent a summer day in New Orleans? Describe what those dewpoints mean and why you answered the way you did? Which place is dry and which one is humid? How can you tell by the dewpoint?
Problem 3: Look at the image of the USA below. Describe in detail, why there are so many deserts in the western half of the USA, especially east of the Sierra Nevada, CA and the Rocky Mountains. (it's not land/sea heating)
