← GeographyWhich outcome is linked to decreased temperature differences, affecting circulation cells?
A)Weakened mid-latitude jet streams✓
B)Increased frequency of strong hurricanes
C)Amplified polar vortex destabilization
D)Strengthened ocean current upwelling
💡 Explanation
Weaker temperature gradients reduce the pressure gradient force, weakening the geostrophic balance, which is geostrophic wind. Therefore, weakening Hadley Cell circulation reduces mid-latitude jet stream strength, rather than strengthening other atmospheric or oceanic flows because other systems are driven somewhat differently.
