Seasonal Patterns

Location of the sun’s noon-time vertical rays (i.e., where the sun is directly overhead) helps to control the position of the ITCZ

Northern Hemisphere summer, ITCZ and all of the wind and pressure belts migrate to the north

North Hemisphere winter, ITCZ and all of the wind and pressure belts migrate to the south

Climate Change Detection

  • Is the Earth’s Current Climate Changing?

  • If so, what evidence can you provide?

  • (We will discuss the question of attribution in a bit.)
