Which effect occurs when trade winds weaken in the Pacific Ocean?

💡 Explanation

When trade winds weaken, diminished Coriolis force-driven upwelling occurs because equatorial currents shift, leading to less cold water reaching the surface and a deepening of the thermocline in the eastern Pacific. Therefore, increased thermocline depth results, rather than intensified upwelling, decreased temperatures, or strengthened cyclonic activity, which require stronger trade winds.
