← GeographyWhich climatic shift occurs when weakened trade winds disrupt equatorial ocean currents during strong El Niño events?
A)Increased upwelling along Peruvian coast
B)Enhanced monsoons in the Indian subcontinent
C)Severe drought in the Indonesian region✓
D)Decreased hurricane activity in Atlantic
💡 Explanation
When trade winds weaken during El Niño, thermocline elevation changes because the surface ocean heat distribution, normally pushed westward, redistributes, leading to suppressed convection and rainfall in Indonesia. Therefore drought occurs, rather than coastal upwelling which normalizes due the weakening, enhanced monsoons which occur in other regions, or the decreased activity from changing sheer patterns.
