Final answer:
The width of the Hadley cell is expected to decrease due to atmospheric circulation changes.
Step-by-step explanation:
The width of the Hadley cell is expected to decrease due to atmospheric circulation changes. The Hadley cell is a large-scale atmospheric circulation pattern that spans between the equator and 30 degrees latitude. It consists of warm air rising at the equator, moving towards the poles, sinking at around 30 degrees latitude, and returning towards the equator along the surface.
As global warming and climate change affect the Earth's temperature, it can lead to changes in atmospheric circulation. One of the expected changes is a narrower width of the Hadley cell. This narrowing is thought to be caused by changes in temperature gradients between the equator and the poles, which can result in altered wind patterns and a decrease in the width of the Hadley cell.
