Which outcome occurs when upper tropospheric winds accelerate due to temperature differences across Hadley cell boundaries?

💡 Explanation

When upper tropospheric winds accelerate, a stronger subtropical jet stream forms because thermal wind balance dictates that wind speed is proportional to the horizontal temperature gradient, leading to increased atmospheric subsidence over the subtropics, inhibiting precipitation. Therefore subtropical desertification increases, rather than alternative effects tied to polar stability, ocean circulation, or ozone depletion, which rely on different mechanisms.
