Which outcome occurs when multiple Hadley cells merge?

💡 Explanation

Intensified subtropical desertification occurs because the descending air in Hadley cells suppresses precipitation, and merging increases this effect via adiabatic compression, creating arid conditions via subsidence, therefore deserts worsen, rather than other cell formation changing.
