Which mechanism causes expansion of subtropical desert regions due to atmospheric circulation?

💡 Explanation

When air rises near the equator it cools aloft before descending in subtropical regions due to Hadley cell circulation and adiabatic compression, resulting in warming and drying. Therefore subsidence and heating expands deserts rather than rain shadow, El Niño, or polar jet stream displacements that operate through different processes.
