When land cools at night, the air near the surface becomes cooler and denser, so it sinks and raises the land’s surface pressure relative to the sea. Cooler, higher-pressure air then moves toward the sea to replace the air over the water, creating a breeze that flows from land to sea—the land breeze. This contrasts with a sea breeze, which happens in the daytime as the land heats up and air rises there, drawing in cooler air from the sea. Santa Ana winds are a specific warm, downslope wind in southern California, not this cooling-over-land effect. Katabatic winds are gravity-driven drainage winds down slopes from high terrain, which is a different setup from the coast-driven land-to-sea flow described here.
