Which mechanism causes increased coastal aridity when cold ocean currents circulate near landmasses?

💡 Explanation

When cold ocean currents circulate near landmasses, atmospheric stability increases near the surface inhibiting convection because the cool air suppresses upward motion needed for condensation and cloud formation. Therefore reduced cloud formation leading to less coastal rainfall results, rather than subsidence, altered thermohaline dynamics or coriolis-induced wind changes which acts differently.
