Which climatic response increases when weakened trade winds reduce upwelling during an El Niño event?

💡 Explanation

When trade winds weaken during an El Niño, upwelling decreases because reduced surface water divergence limits the ascent of cold, nutrient-rich water, causing warming in the eastern Pacific and increased convective precipitation. Therefore rainfall over the Eastern Pacific increases, not cooling in the West, gulf hurricanes, or a strengthened jet stream, elements requiring separate atmospheric conditions.
