Which shift in global precipitation patterns is caused by the enhanced Hadley cell effect due to rising temperatures?

💡 Explanation

When temperatures rise, the increased evaporation amplifies Hadley cell circulation because warmer air holds more moisture, leading to increased precipitation at the equator and drying at subtropical latitudes. Therefore, the expansion of arid zones at 30° latitude results, rather than increased subtropical rainfall, weakened monsoons, or declining polar precipitation, which require different climate forcings.
