Which risk increases when atmospheric jet streams weaken?

💡 Explanation

Weakened jet streams promote Rossby wave amplification, so high-and-low pressure systems stall because the reduced pressure gradient weakens the geostrophic wind effect; therefore anomalous weather becomes likelier rather than fluvial, glacial, or algal changes.
