Which outcome results when high-latitude upper-atmosphere cooling intensifies?

💡 Explanation

Increased cooling drives atmospheric pressure differences because isobaric surfaces slope more steeply enhancing the meridional temperature gradient. Stronger temperature gradients intensify pressure gradients; therefore, steeper gradients enhance jet streams rather than weaken Hadley cell circulation.
