How Does the Ocean Influence the Weather on Land?

The ocean is like a giant heater or cooler for the air. When it’s warm, it gives heat to the air above it, which then moves toward land and makes the weather warmer. When it’s cold, it takes heat from the air, making the weather cooler. This happens all year round and affects places far away from the ocean.

The Big Picture

Think of the ocean as a giant bathtub. If you put your hand in warm water, the water feels warm. Similarly, when the ocean is warm, it makes the air above it warm too. That warm air moves to land like a big, invisible wave.

When that warm air reaches land, it brings rain and storms, just like when you take your hand out of hot water and feel the heat spread across your skin.
