Which of the following is added to the assumptions of the single cell model of global circulation to create the three cell model? a. Earth axis tilt
b. Earth rotation
c. Land masses
d. Seasonal wind shifts

Answer and Explanation:

Atmospheric circulation is the large-scale movement of air and also through which heat is distributed on the surface of the Earth. It describes how air moves across the planet in a specific pattern. It is how heat is redistributed around the globe.

3 cells make up the Global Atmospheric Circulation Model which are the following:

1.Hadley

2.Ferrell

3.Polar

Polar Cell stretches over the North and South poles, having its boundary at around 60° North and South. Ferrell Cell stretches between 30° and 60° North and South and Hadley Cell stretches between the Equator (0°) and 30° North and South.

We assume the seasonal shift of wind to create the single-cell model of global circulation to create the three-cell model.

The movement of air is caused by heat differentiation. It means that the sun heats the earth unevenly and the Equator receives the most concentrated dose of heat.
