What is global circulation? | Part One | Differential heating
The climate we experience and the location of the world’s deserts and rainforests are controlled by how air moves around the globe, a process known as Global Circulation.
What is global circulation? | Part Two | The three cells
Global circulation on our rotating Earth splits the atmosphere into three cells in each hemisphere: the Hadley cell, Ferrel cell and Polar cell. In this video, we look at how air moves around each cell and how this controls the location of the world’s deserts and rainforests.
