Formative Assessment 4: Hadley Circulation

Instructions

  1. Use the diagram of temperature vs. air mass moisture content below to plot the trajectory of the initially warm, tropical air rising at the equator and cycling through the Hadley cell. Assume that the tropical air mass has a temperature of 35 °C and relative humidity of 90% (calculate the water content), track the airmass to the top of the atmosphere and to roughly 30 degrees North latitude then have it descend to sea level. Plot each point of change on the graph.
  2. Now, what can you say regarding the occurrence of desert environments at about 30 °N and S?
