← GeographyWhich outcome occurs when polar jet stream meanders increase?
A)Enhanced Rossby wave formation✓
B)Reduced ocean upwelling intensity
C)Decreased thermohaline circulation rates
D)Stabilized Hadley cell boundaries
💡 Explanation
Enhanced “Rossby wave formation” occurs because increased meandering strengthens vorticity, resulting in larger amplitude Rossby waves and amplified temperature swings; therefore enhanced wave effects, rather than stabilized conditions, spread further because destabilization initiates disturbances.
