Which process causes coastal upwelling to cease temporarily along the Peruvian coast?

💡 Explanation

When Pacific trade winds weaken, El Niño conditions develop because reduced wind-driven ocean circulation diminishes upwelling, leading to warmer surface waters. Therefore upwelling ceases temporarily, rather than stronger currents, fog thickening or sedimentation, which alter different conditions of nutrient flow from the deep ocean.
