← GeographyWhich airflow pattern alteration occurs when air ascends rapidly at the Intertropical Convergence Zone?
A)Weakened upper-level Coriolis effect✓
B)Enhanced surface albedo reduction
C)Decreased tropospheric ozone concentration
D)Strengthened subtropical jet stream convergence
💡 Explanation
When rapid air ascent occurs at the ITCZ, vertical motion dominates over horizontal, weakening the Coriolis effect aloft because the deflection only occurs with sustained horizontal movement. Therefore, the Coriolis effect weakens, rather than albedo reduction, ozone loss, or jet stream convergence which are caused by different atmospheric mechanisms.
