Which weather outcome results when subtropical high pressure systems force descending air?

💡 Explanation

Arid conditions develop because subtropical high pressure causes adiabatic compression as air descends, resulting in the Warm Dry Air Descending mechanism. This suppresses precipitation; therefore deserts form downwind, rather than rainforests which require rising moist air for condensation.
