Which consequence results when a polar jet stream meanders significantly?

💡 Explanation

Extreme temperatures result from a meandering jet stream, because **Rossby wave propagation** shifts large air masses unusually far south or north; therefore anomalies occur rather than a normal seasonal variation due wave location effects.
