← GeographyWhich flow regime results from increased geostrophic balance deviation?
A)Enhanced Hadley cell symmetry
B)Weakened subtropical jet stream
C)Increased Rossby wave amplitudes✓
D)Stratospheric polar vortex collapse
💡 Explanation
Increased variance arises because ageostrophic winds intensify due to pressure imbalances; increased Coriolis deflection amplifies wave amplitudes rather than maintaining zonal balance. Resulting Rossby waves dominate, therefore option C is accurate, rather than alternatives.
