Which outcome results in coastal regions during increased intensity of subtropical high-pressure cells?

💡 Explanation

Strengthened high-pressure cells intensify the pressure gradient promoting Ekman transport, driving offshore surface water which is replaced by deeper, nutrient-rich waters because of coastal upwelling; therefore increased marine productivity, rather than diminished upwelling or coastal erosion rate increase results.

• Which deflection results when a pressure gradient drives horizontal equatorial airflow?
• Which risk increases when tectonic uplift obstructs glacial meltwater flow?
• Which mechanism establishes atmospheric stability within the polar cell circulation pattern?
• Which geomorphic risk is most amplified when infrastructure development disrupts thermokarst processes within permafrost regions?
• Which risk increases when artificial levees constrict a river's floodplain during an extreme rainfall event?
• Which outcome occurs when polar cells weaken disproportionately?
