The ocean is called the energy reservoir and regulator of the earth's weather and climate. Do you know why?

Most of the solar radiation reaching the earth is absorbed by the ocean, which has great specific heat capacity and mass, so it constitutes a pure natural energy pool. The three states of water, solid, liquid and gas, can be converted to each other, and heat is generated and lost during the conversion process. When the temperature is too high, the water on the ocean surface will evaporate, and when the temperature is too low, the ocean surface will freeze, so the ocean has strong adjustment ability.

First, introduce the concept of ocean. Ocean is the general name of the most extensive water body on the earth. The vast water body that is separated by various continents is called ocean, and the ocean in the ocean refers to the central part of the ocean, while the sea is the marginal part. The sea area on the earth accounts for about 71% of the earth's surface area, and the water in the ocean accounts for 97% of the total water on the earth, but only 2% can be used for human drinking.

In tropical areas, because of the strong direct solar radiation, there is a surplus of energy in the ocean, so the water temperature near the equator is significantly higher than that in high-latitude marine areas. The warm current in the ocean flows from the equator to the high latitude, while the cold current in the high latitude flows to the equator in a large-scale circulation, which causes the re-release of energy, which makes the temperature in the equatorial region and the poles not too different. In addition, the ocean also transports a lot of energy and water vapor to the atmosphere, so there is an exchange of heat, momentum and substances between the ocean and the atmosphere, and the interaction between the sea and the atmosphere can cause ever-changing weather and climate phenomena or extreme events. It can be said that the ocean participates in the process of material and energy balance on the whole earth surface and becomes an indispensable part of the whole climate system.

The ocean has a great relationship with global warming. First, the global temperature rises sharply, and the ocean absorbs 9% of the heat generated by climate change. Global warming also causes the sea level to rise. The warming of seawater is uneven, because the heat flows around the world under the action of water flow. Because the ocean has the function of stabilizing temperature, a lot of energy generated by human beings is absorbed by the ocean.
