Key Idea.
Section 1
Energy Moves Between Substances
Nature seeks balance. When two substances of different temperatures interact, energy transfer occurs spontaneously. The direction is always the same: from the warmer substance to the colder one.
This transfer continues until thermal equilibrium is reached. In the climate system, this fundamental law drives the exchange of heat between the massive reservoirs of the ocean and the atmosphere.
Section 2
Warm Ocean Currents Warm Coastal Air
Warm ocean currents act as heaters for the planet. Originating near the equator, they carry vast amounts of thermal energy toward the poles.
When these warm currents flow past cooler regions, they release their energy into the atmosphere. This transfer warms the air above the water, giving coastal cities significantly milder winters than inland areas at the same latitude.
Section 3
Cool Currents Absorb Energy from Air
Conversely, cooler ocean currents flow from the poles toward the equator. Because the water is colder than the surrounding air, energy flows from the air into the water.
The ocean effectively absorbs the heat, removing energy from the atmosphere. This process cools the coastal air, creating refreshing, cooler climates in regions influenced by these currents.
