How does the ocean regulate the earth's climate?
Sunlight shines on the earth in the form of short-wave radiation. When it passes through the atmosphere, only a small part of it is directly absorbed by the atmosphere, and most of it shines on the earth's surface, raising the temperature of the earth's surface. When the earth's surface warms, it will emit radiation continuously. This radiation is different from the short-wave radiation of the sun. It does not give off light, but only gives off heat, which belongs to long-wave radiation, also called thermal radiation. This long-wave radiation is easily absorbed by the atmosphere, so the atmospheric temperature rises.
The ocean accounts for 2/3 of the earth's area and is the main supplier of atmospheric heat; At the same time, the heat capacity of seawater is much greater than that of air. When the seawater temperature of 1cm3 decreases 1℃, the air temperature of 3000cm3 increases 1℃. Seawater is a transparent fluid, and sunlight can reach deeper places, so that a fairly thick water layer stores heat. If the global surface seawater with a thickness of 100 m cools 1℃, the released heat can raise the global atmosphere by 60℃. Therefore, a large amount of heat energy accumulated in the ocean for a long time is like a "boiler", which has a certain impact on the weather and climate through energy transfer.
