Which atmospheric consequence occurs when polar cell weakening develops?

💡 Explanation

Greater mid-latitude temperature volatility results because a weakened polar cell reduces the poleward heat transport via disruptions in advection; therefore, greater volatility occurs with increased likelihood of extreme weather, rather than enhanced ocean upwelling.
