Which atmospheric outcome is directly caused by the descending air within Hadley cells?

💡 Explanation

When descending air within Hadley cells occurs, atmospheric compression increases, inhibiting cloud formation because the air warms and dries, leading to arid climates at approximately 30 degrees latitude. Therefore arid climates result because of sinking motion, rather than salinity, upwelling, or jet streams, which involve other atmospheric or oceanic mechanisms.
