Which phenomenon causes increased coastal aridity when intensified subtropical gyre circulation upwells cold water?

💡 Explanation

When subtropical gyre circulation intensifies, enhanced upwelling of cold, deep water decreases the sea surface temperature and thus surface air temperatures because colder air has a lower capacity to hold moisture, resulting in drier coastal climates. Therefore, reduced atmospheric moisture capacity results, rather than increased fog, inland rain, or weakened breezes which are controlled by gradients and pressure systems.
