Which phenomenon results when trade winds weaken in the Pacific Ocean preventing upwelling in an established gyre?

💡 Explanation

When trade winds weaken, normally they drive upwelling within gyres, a reduction in this process occurs because prevailing wind patterns are disrupted, leading to a decrease in the supply of deep, nutrient-rich water. Therefore, reduced nutrient availability results, rather than fog, erosion, or sequestration each requiring separate climate mechanisms.
