The ocean is closely related to the climate. How does it affect the weather?
Ocean is one of the driving factors of ocean current, and ocean current is not only the simple flow of seawater, but also transports heat and water vapor. Generally speaking, warm current will increase temperature and humidity, while cold current will decrease temperature and humidity. The coastal zone where warm current flows is generally humid, and the coastal zone where cold current flows is often desert. For example, the average winter temperature in western Europe, Britain, France and other countries is above 0 degrees, and the North Atlantic warm current is indispensable. If the ocean current disappears one day, it will be colder in winter 10 degrees. The distribution of nearly a thousand kilometers along the Atacama desert in South America is directly related to the cold current in Peru.
In addition, the change of ocean current intensity will also cause El Ni? o and La Ni? a phenomena (equatorial countercurrent and Peruvian cold current), which will cause natural disasters such as drought, rainstorm and forest fires in many areas.
Warm current refers to the humid climate extending to high latitudes and low latitudes extending to high latitudes. Compared with high latitudes, the humidity and temperature in low latitudes are higher, so the warm current will increase the temperature and humidity along the coast.
On the other hand, the cold current extends the dry climate to low latitudes. Compared with low latitudes, high latitudes have low temperature and dry climate, so the cold current will cool and dehumidify the coastal areas.
People discovered this feature and used it effectively. The most typical example is that when cultivating seedlings in agricultural production, in order to prevent seedlings from freezing at night, more water is put into the seedling field at night, and when the water in the seedling field is hot at night, the temperature will not drop too low to prevent seedlings from freezing. The next morning, part of the water in the paddy field was drained to let the paddy field bask in the sun, so that the temperature could be higher, which was beneficial to the growth of seedlings.
