Which effect contributes to desert formation along the western coasts of continents associated with strong subtropical gyres?

💡 Explanation

When subtropical gyres circulate, the eastern boundary currents experience coastal upwelling, because wind-driven surface waters are deflected offshore, replaced by cold, deep water, stabilizing the atmosphere suppressing precipitation. Therefore, deepwater upwelling of cold currents contributes to on-shore desert formation, rather than enhanced evaporation, increased cyclone precipitation,or reduced aerosols which promote cloud formation and precipitation.
