Which outcome occurs when rapid polar ice melting strengthens temperature gradients?

💡 Explanation

Increased high-latitude temperature gradients enhance baroclinicity, intensifying the meandering of Rossby waves because differential heating drives their amplitude increase, therefore creating amplified waves rather than stable atmospheric patterns under weaker gradients.

• Which mechanism causes lahar formation on stratovolcano slopes after heavy rainfall?
• Which mechanism causes increased flood risk when an alluvial fan experiences rapid urbanization?
• Which mechanism causes the rapid uplift of land during a large subduction earthquake along a megathrust fault?
