Which model is used as a simplified explanation for the redistribution of energy from surplus to deficit areas?

Which model is used as a simplified explanation for the redistribution of energy from surplus to deficit areas?

• A. Four cell model
• B. Two cell circulation
• C. Three cell model
• D. Single cell system

Answer: (C)

The main idea here is how the atmosphere transports heat from the equator toward the poles. The three-cell model provides a simple, workable framework for this, showing three circulation loops in each hemisphere: a Hadley cell near the equator with rising warm air and trade winds, a Ferrel cell in the mid-latitudes with westerlies, and a Polar cell near the poles with cold air and polar easterlies. This arrangement explains why heat moves poleward and why we see the characteristic wind belts and pressure systems at different latitudes, helping to account for tropical rainfall, subtropical deserts, and the mid-latitude climate. It’s used because it balances simplicity with enough realism to describe the main patterns of heat redistribution. A single-cell model is too crude to explain the mid-latitude westerlies; a two-cell model misses the distinct mid-latitude circulation, and a four-cell approach, while more detailed, goes beyond the basic explanatory framework for this question.
