Which outcome occurs when persistent atmospheric high-pressure systems block coastal upwelling currents?

💡 Explanation

When high-pressure systems persist, they reduce wind-driven upwelling because they suppress the winds needed to move surface waters offshore, which allows deeper, nutrient-rich water to rise. Therefore a decline in phytoplankton blooms results, rather than increased fog, a stronger thermocline, or intensified erosion which require different oceanographic or meteorological conditions.
