Which mechanism causes the cooling effect in coastal upwelling zones when winds drive surface water offshore?

💡 Explanation

When winds drive surface water offshore, upwelling brings colder water from the deep ocean to the surface; evaporation occurs because latent heat is absorbed, cooling the surface. Therefore, latent heat absorption causes surface cooling, rather than conduction, advection, or radiation, which are subordinate effects in upwelling.
