Which regional drought risk increases during El Niño?

💡 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.
