The role of ocean in regulating climate

The role of the ocean in regulating climate is as follows:

Compared with land, marine ecosystem regulates global water circulation and promotes water balance through evaporation, water vapor transport and precipitation. Marine ecosystem can adjust the temperature, and by absorbing and releasing a lot of heat, it can adjust the global atmospheric temperature.

The ocean is the source of wind and rain, and it is a huge "regulator", which is very important for stabilizing the climate. However, according to the recent climate statement issued by the World Meteorological Organization, 2020 is one of the warmest three years since meteorological records began, global ocean warming continues, and ocean heat reaches a new high.

Specific introduction:

The ocean plays a very important role in atmospheric movement and climate change. The ocean current movement in the ocean and the thermal difference between land and sea have shaped different natural landscapes and complex weather and climate phenomena on the earth. For example, the North Atlantic warm current has brought beautiful ecological environment and superior lifestyle to some Nordic countries, and the East Asian monsoon climate and South Asian monsoon climate have brought favorable weather to agricultural production in Asian countries.

According to Su Jingzhi, a researcher at China Institute of Meteorological Science, the ocean plays an important role in regulating the global weather and climate system, which can regulate the weather and climate conditions of the earth, such as temperature and humidity. Because the thermal inertia of the ocean is relatively large, the thermal storage capacity of seawater with the same volume is more than 2000 times that of the atmosphere.

If there is no ocean, the temperature difference between day and night, winter and summer on the earth will be great, and the temperature will fluctuate greatly, which may not be suitable for human habitation.

Future phenomena:

In the future, the abnormal sea level rise in more areas will be more frequent, and the increasingly frequent high water level will have a serious impact on many areas. With the warming of the ocean and the decrease of sea ice, the biomass, yield and fishing potential of global marine animal communities will decrease, and the species composition will also change; The risk of coastal and low-lying areas suffering from adverse effects such as floods, coastal floods and coastal erosion will increase.
