Question

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 1

The Earth's rotation is added to the single cell model to create the more complex three cell model of global circulation, accommodating the Coriolis effect.

Step-by-step explanation:

To transform the single cell model of global circulation into the three cell model, one of the key factors that is added is the Earth's rotation. The three cell model accounts for the Hadley, Ferrel, and Polar cells, which are driven by both the heating of the Earth's surface and the rotation of the Earth, known as the Coriolis effect. This rotation causes moving air to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere, creating wind patterns that are more complex than those predicted by the single cell model.

Answer 2

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.
