Unformatted text preview: SAN FRANCISCO STATE UNIVERSITY Department of Geography & Human Environmental Studies Geog 101: Our Physical Environment Exercise 2: Atmospheric moisture N a m e : This exercise is an introduction to using concepts of humidity learned in class and from the text (Chapter 7) to explain phenomena such as cloud development and variability in relative humidity experienced around the Earth. This exercise works on analytical and graphing skills. Make sure you understand the following concepts before you start: • Maximum humidity, absolute humidity, relative humidity and dew point temperature • Saturation, condensation, lifting mechanisms and cloud formation A) Maximum humidity Below is a graph of the relation between air temperature and the amount of water vapor that can be held by that air (saturated vapor pressure). The x-axis or independent variable is air temperature (T air , units = °C) and the y-axis (dependent variable) is saturated vapor pressure (e s , units = mb). 10 20 30 40 50-30 -25 -20 -15 -10-5 5 10 15 20 25 30 35 Temperature (degC) Saturated vapor pressure (mb) What is the saturated vapor pressure at 0 °C: ________________, at 20°C: __________________ What is the difference in saturated vapor pressure between -30 and -10 °C? __________________ What is the difference in saturated vapor pressure between 10 and 30 °C? ___________________ What is the basic relationship between air temperature and the capacity of air to hold water vapor?...
