Which mechanism amplifies latitudinal temperature differences when Hadley cell boundaries fluctuate significantly?

💡 Explanation

When Hadley cell boundaries fluctuate, the varying extent of desertification modifies albedo, causing albedo feedback because increased reflectivity reduces absorbed solar radiation, amplifying cooling in the polar regions which increases the latitudinal temperature gradient. Therefore albedo feedback is amplified, rather than Ekman transport, evapotranspiration, or orographic lift, each requiring different mechanisms and conditions.
