                   Chapter 5
Learning Objectives

 Be able to identify and explain how the different
  temperature controls operate.


 Be comfortable with reading temperature maps for
  January and July and explaining them.
Factors Controlling Temperature

 Latitude
   Affects insolation


 Altitude
   High altitude has greater daily range
   High altitude has lower annual average


 Cloud Cover
   Variable albedo
   Moderate temperatures – cooler days, warmer nights
