Which mechanism amplifies temperature gradients at mid-latitudes when polar Hadley cell boundaries shift equatorward?

💡 Explanation

When Hadley cell boundaries shift equatorward, the region of maximum outgoing longwave radiation expands poleward while incoming solar radiation remains concentrated near the equator, leading to increased regional differences Radiative cooling imbalance exacerbating temperature gradients. Therefore enhanced radiative amplifies temperature contrasts rather than alternative choices resulting.
