Which effect increases continental aridity within subtropical zones?

💡 Explanation

Descending air suppresses precipitation because adiabatic heating increases the air parcel's water-holding capacity; this is the Hadley cell circulation effect. Therefore, dry conditions result directly from descending air, rather than other processes happening elsewhere.
