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