← GeographyWhich regional drought risk increases during El Niño?
A)Indonesian Archipelago seasonal rainfall reduction✓
B)North Atlantic deep water formation decreasing
C)Amazon rainforest nutrient upwelling declines
D)Saharan dust dispersal to Americas
💡 Explanation
El Niño causes a shift in atmospheric pressure, which reduces trade winds, meaning Walker circulation weakening causes less moisture transport towards Indonesia, because the normally ascending air shifts eastward; therefore drought is more likely, rather than increased rainfall.
