Which outcome occurs when the descending air in a Hadley cell is significantly drier than average?

💡 Explanation

When drier-than-average descending air occurs, adiabatic compression ensues which reduces rainfall, increasing temperature because of low specific heat. Therefore, increased desertification results, rather than increased jet stream oscillation, a weakened Coriolis effect, or extensive flooding, which require different climatological preconditions.
