Which risk increases when powerful jet streams meander significantly?

💡 Explanation

Temperature extremes are amplified because atmospheric blocking disrupts typical west-east weather patterns due to Rossby waves. Therefore, regions under the block experience prolonged temperatures, rather than normal seasonal variation, intensifying heatwaves or cold snaps.
