Which change occurs in global precipitation patterns when Hadley cells widen due to polar warming?

💡 Explanation

When Hadley Cells widen as a result of polar warming, there is increased subsidence in the subtropics because the descending branch shifts poleward, increasing desertification, especially near the equator. Therefore, equatorial desertification increases, rather than increased rainfall, a thinning ITCZ, or higher temperate zone rainfall, which would result from other circulation shifts.
