Which outcome is intensified by increased Equatorial upwelling during La Niña?

💡 Explanation

La Niña strengthens upwelling, which increases the concentration of nutrient-rich deep ocean waters at the surface via advection, because reduced thermocline depth brings up nutrients. Therefore, nutrient concentration increases, rather than decreasing temperatures or causing flooding that characterizes El Niño.
