Download Atmospheric Moisture: Review Questions on Evaporation, Condensation, Saturation, and Humid and more Study notes Meteorology in PDF only on Docsity! Jon Ahlquist 10/5/2006 MET1010 Intro to the Atmosphere 1 Chapter 4 Review: Moisture What do you call the direct transformation from ice to vapor? From vapor to ice? Explain why it would be very unusual if only evaporation were taking place without some condensation occurring at the same time and place. What is saturation? What is correct and what is incorrect about the statement: Warm air can hold more water vapor than cold air. What is vapor pressure? Saturation vapor pressure? What happens to the saturation vapor pressure as temperature increases? Boiling, Dew Point Temperature The saturation vapor pressure equals what other pressure when water boils? What happens to the boiling temperature as you go to higher altitudes? Why does this happen? What is the definition of relative humidity? What is the definition of dew point temperature? Can the dew point temperature be lower than the air temperature? Equal to the air temperature? Greater than the air temperature? How much does the dew point temperature usually change during 24 hours? Describe how relative humidity changes during a day. Dew Point and Relative Humidity How are the dew point and the air temperature related when the relative humidity is near 100%? When the relative humidity is low? What is true about the dew point when air has many water vapor molecules? Can air have: a low relative humidity & a low dew point? a low relative humidity & a high dew point? a high relative humidity & a low dew point? a high relative humidity & a high dew point? Humidity in Different Places Why does Florida air usually have a higher dew point temperature than California air? Why does your skin get dry during winter, particularly up north? Why is it vague to say that the air in a certain place is humid? (dew point versus relative humidity) What fraction of evaporation occurs over oceans? If all the water vapor in the atmosphere, would rain out (an impossibility), how deep would it be over the surface of the Earth? What region of the continental US typically has the highest dew point temperatures? Relative Humidity and Measurement Describe situations in which you cold find the following relative humidities outside & inside a house: Low outside and low inside Low outside and high inside High outside and low inside High outside and high inside How could you measure the dew point temperature? How does a psychrometer (2 thermometers, one covered by a wet cotton sock) measure humidity?
