Does the ocean affect climate and weather? Generally speaking, what is the impact?

The ocean is closely related to our weather and climate change. The interaction between the ocean and the atmosphere, such as heat, momentum and material exchange, can lead to changes in weather and climate phenomena or extreme events, such as typhoons, thus leading to global or regional climate anomalies and meteorological disasters. The ocean plays a very important role in atmospheric movement and climate change. The internal movement of ocean currents and the thermal difference between land and sea have shaped different styles of natural landscapes and complex and diverse climate and weather phenomena on the earth.

The ocean plays an important role in regulating the global weather and climate system and the weather and climate conditions of the earth. Due to the thermal inertia of the ocean, the same volume of water can store more than 2000 times of atmospheric heat. The temperature difference between the ocean and the earth between day and night, between winter and summer, and the temperature fluctuation are too great for human habitation. Some data show that the ocean provides 90% of the rainfall on the earth, absorbs 90% of the excess heat, and redistributes it around the world through ocean currents, so that the earth will not be lukewarm all the time.

In recent decades, the ocean has been warming, extending from the sea level to the seabed for more than 2000 meters. In recent years, the frequency of ocean heat waves has increased significantly, and the ocean temperature has even increased by about 4℃, lasting for more than several months. The temperature of seawater is very small, but once or twice it can have a great impact. The rise of high temperature will seriously affect the marine ecology and the survival of fish and algae. In particular, the ocean stores a lot of excess heat at a depth of more than 2000 meters. Eventually, decades or even centuries later, heat will return to the surface. Considering that the earth's surface temperature will be much higher at that time, the rise of ocean heat will lead to the secondary increase of global temperature, which will have a more serious impact on the global climate, so the delay effect of ocean heat should be considered.

Experts say that with the increasing impact of climate change, it is more important than ever to observe the ocean with higher accuracy and understand its climate code. At the same time, the public should take the initiative to realize the important role of the ocean in the earth's climate system, reduce greenhouse gas emissions, and take a green and low-carbon development path.
