← GeographyWhich climate effect results when the Intertropical Convergence Zone (ITCZ) annual oscillation is restricted to a narrow latitudinal band?
A)Pronounced monsoonal rainfall patterns✓
B)Weakening of the polar jet stream
C)More frequent El Niño events
D)Enhanced extratropical cyclone formation
💡 Explanation
Pronounced monsoonal rainfall patterns emerge because the concentration of solar heating drives strong thermal gradients and regional circulation, resulting in seasonal wind reversals. Therefore, monsoons intensify, rather than generating jet stream changes, El Niño frequency, or extratropical cyclones which are affected by different processes.
