Which outcome occurs when prolonged atmospheric blocking disrupts zonal wind streams?

💡 Explanation

Jet stream meandering is amplified because Rossby waves, established via baroclinic instability, grow larger with stalled zonal flow. Stronger meanders cause extreme weather rather than predictable upwelling. Therefore, option B is best, rather than alternatives affecting ocean currents or the stratosphere.
