What effect does Kuroshio have on the climate?

In China, some people compare the Kuroshio to a "drought and flood forecaster". Because of the shift of Kuroshio flow position, it has obvious influence on the weather drought and flood in coastal areas of China.

In 1953, the Kuroshio deviated from its orbit all the year round and moved southward about 170 km. The following year, a once-in-a-century flood occurred in the Jianghuai Valley of China.

1957 deviated from the normal track again, and the average position moved northward, resulting in severe drought in the Yangtze River basin.

1958, turning north again. Results Drought occurred again in the Yangtze River basin and waterlogging occurred in North China.

A similar situation has happened several times. Through the research of meteorologists in China, the regularity has been found.

It turns out that ocean water temperature has a direct impact on the atmosphere. According to scientists' calculations, 1 cubic centimeter of seawater can reduce the heat released at 2℃ and increase the air temperature by more than 3000 cubic centimeters. But seawater is transparent, and solar radiation can reach deeper places, so that a fairly thick water layer stores heat. If the global 100-meter-thick seawater is reduced to 1℃, the released heat energy can raise the global atmosphere by 60℃. It can be seen that a large amount of heat energy accumulated in the ocean for a long time has become a huge "hot station", and through the long-term accumulation of a large amount of heat energy, it has become a huge "hot station", which constantly affects the changes of weather and climate through energy transfer. In addition, there is an obvious temperature difference between the high temperature Kuroshio and the relatively low temperature seawater in the north, forming a strong ocean front. Through the interaction between ocean and atmosphere, the climate will change. The atmospheric front is the place where cold and warm air meet, so it is also the area of rainfall. Therefore, when the Kuroshio moved southward in 1953, the ocean front also moved southward, making the atmospheric front and rain belt move southward accordingly. In the second year, rainfall in the Jianghuai basin increased and floods occurred. 1957 and 1958, after the Kuroshio moved northward, the atmospheric front and rain belt also moved northward accordingly, resulting in the vacancy and drought of Meiyu in the Yangtze River basin.

Although part of the Gulf Stream comes from the Gulf of Mexico, most of it comes from the Caribbean. When the southern and northern equatorial currents meet in the western Atlantic Ocean, they enter the Caribbean Sea, pass through the Yucatan Strait, a small part of them enter the Gulf of Mexico, and then flow along the coast of the Gulf of Mexico. Most of the current turns sharply eastward and enters the Atlantic Ocean from straits of florida, USA. The Gulf of Mexico, which first entered the Atlantic Ocean, flows north, then rapidly flows northeast, crosses the Atlantic Ocean, flows to the offshore of northwest Europe and flows into the cold Arctic Ocean. Its thickness is 200 ~ 500m, its velocity is 2.05m/s, and the water transported is 1.5 times that of Kuroshio.
